Continuous autotype script?

Question

I'm looking for something to what I am using below (You've all probably seen the below code before), but that waits for a button press to continue to a line if the text is too long, and a way to recognize when all text has been displayed.

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class AutoType : MonoBehaviour {
 
     public float letterPause = 0.2f;
     
     private Text text;
 
     string message;
 
     void Start()
     {
         text = GetComponent<Text>();
 
         message = text.text;
         text.text = "";
         StartCoroutine(TypeText());
     }
 
     IEnumerator TypeText()
     {
         foreach (char letter in message.ToCharArray())
         {
             text.text += letter;
             gameObject.GetComponent<AudioSource>().Play();
             yield return 0;
             yield return new WaitForSeconds(letterPause);
         }
     }
 }

This is my first time posting here so sorry if I've done something wrong.

There might be a way to check if the message doesn't fit in the UI.Text, but I'm not sure how. So here I'm simply counting the number of chars in the message.

I changed the foreach-loop to a for-loop.
Created a function that determines if the message being displayed is full, you'll want to rewrite or expand on this.

Also created a coroutine that will wait for user input.

     // A coroutine that will loop until a key is pressed
     IEnumerator WaitForInput() {
         while (!Input.anyKey)
         {
             yield return null;
         }
         yield return null;
     }
 
     //Determines if message will fit 
     //TODO: return true if last word in message exceeds limit
     bool IsDisplayMessageFull(int i) {
         int maxLettersToShow = 8;
         
         if (i != 0 && i % maxLettersToShow == 0) return true;
 
         return false;
     }
 
     IEnumerator TypeText() {
        for (int i = 0;  i < message.ToCharArray().Length; i++)
         {
             if (IsDisplayMessageFull(i))
             {
                 yield return StartCoroutine(WaitForInput());
                 text.text = "";
             }
 
             text.text += message.ToCharArray()[i];
             gameObject.GetComponent<AudioSource>().Play();
             yield return new WaitForSeconds(letterPause);
         }
     }
