How to make questions random, and include from a folder not inside the unity editor

So I have followed the Unity quiz Game Tutorial and would want to further improve the game. I have wondered how do you make the question in random not in the same order. Also, I would like the questions to be loaded not made inside the Unity Editor.

This is the QuestionData script [System.Serializable] public class AdditionQuestionData { public string questionText; public AdditionAnswerData[] answers; }

And this is the Game Controller using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement; using System.Collections.Generic;

public class AdditionGameController : MonoBehaviour { public AdditionSimpleObjectPool answerButtonObjectPool; public Text questionText; public Text scoreDisplay; public Text timeRemainingDisplay; public Transform answerButtonParent;

 public GameObject questionDisplay;
 public GameObject roundEndDisplay;
 public Text highScoreDisplay;

 private AdditionDataController dataController;
 private AdditionRoundData currentRoundData;
 private AdditionQuestionData[] questionPool;

 private bool isRoundActive = false;
 private float timeRemaining;
 private int playerScore;
 private int questionIndex;
 private List<GameObject> answerButtonGameObjects = new List<GameObject>();

 void Start()
 {
     dataController = FindObjectOfType<AdditionDataController>();                                // Store a reference to the DataController so we can request the data we need for this round

     currentRoundData = dataController.GetCurrentRoundData();                            // Ask the DataController for the data for the current round. At the moment, we only have one round - but we could extend this
     questionPool = currentRoundData.questions;                                            // Take a copy of the questions so we could shuffle the pool or drop questions from it without affecting the original RoundData object

     timeRemaining = currentRoundData.timeLimitInSeconds;                                // Set the time limit for this round based on the RoundData object
     UpdateTimeRemainingDisplay();
     playerScore = 0;
     questionIndex = 0;

     ShowQuestion();
     isRoundActive = true;
 }

 void Update()
 {
     if (isRoundActive)
     {
         timeRemaining -= Time.deltaTime;                                                // If the round is active, subtract the time since Update() was last called from timeRemaining
         UpdateTimeRemainingDisplay();

         if (timeRemaining <= 0f)                                                        // If timeRemaining is 0 or less, the round ends
         {
             EndRound();
         }
     }
 }

 void ShowQuestion()
 {
     RemoveAnswerButtons();

     AdditionQuestionData questionData = questionPool[questionIndex];                            // Get the QuestionData for the current question
     questionText.text = questionData.questionText;                                        // Update questionText with the correct text

     for (int i = 0; i < questionData.answers.Length; i ++)                                // For every AnswerData in the current QuestionData...
     {
         GameObject answerButtonGameObject = answerButtonObjectPool.GetObject();            // Spawn an AnswerButton from the object pool
         answerButtonGameObjects.Add(answerButtonGameObject);
         answerButtonGameObject.transform.SetParent(answerButtonParent);
         answerButtonGameObject.transform.localScale = Vector3.one;

         AdditionAnswerButton answerButton = answerButtonGameObject.GetComponent<AdditionAnswerButton>();
         answerButton.SetUp(questionData.answers[i]);                                    // Pass the AnswerData to the AnswerButton so the AnswerButton knows what text to display and whether it is the correct answer
     }
 }

 void RemoveAnswerButtons()
 {
     while (answerButtonGameObjects.Count > 0)                                            // Return all spawned AnswerButtons to the object pool
     {
         answerButtonObjectPool.ReturnObject(answerButtonGameObjects[0]);
         answerButtonGameObjects.RemoveAt(0);
     }
 }

 public void AnswerButtonClicked(bool isCorrect)
 {
     if (isCorrect)
     {
         playerScore += currentRoundData.pointsAddedForCorrectAnswer;                    // If the AnswerButton that was clicked was the correct answer, add points
         scoreDisplay.text = playerScore.ToString();
     }

     if(questionPool.Length > questionIndex + 1)                                            // If there are more questions, show the next question
     {
         questionIndex++;
         ShowQuestion();
     }
     else                                                                                // If there are no more questions, the round ends
     {
         EndRound();
     }
 }

 private void UpdateTimeRemainingDisplay()
 {
     timeRemainingDisplay.text = Mathf.Round(timeRemaining).ToString();
 }

 public void EndRound()
 {
     isRoundActive = false;

     questionDisplay.SetActive(false);
     roundEndDisplay.SetActive(true);
 }

 public void ReturnToMenu()
 {
     SceneManager.LoadScene("MenuScreen");
 }

}

Help please :) Thanks!!
