How to make a leaderboard in unity using the result JSON of Firebase database

I am using unity3d and Firebase. I can send data to the database, and I can receive it, but I don't know how to use it in the project. I need to transform this json file into an array that has name and score, but I can't get it :(

 {
     "Elisa" : {
       "name" : "Elisa",
       "score" : "53"
     },
     "Javi" : {
       "name" : "Javi",
       "score" : "12"
     },
     "Jon" : {
       "name" : "Jon",
       "score" : "33"
     }
 }

And I using this class

 [Serializable]
 public class Points
 {
     public string name;
     public string score;
 
 
 
     public Points(string _name, string _score)
     {
         this.name = _name;
         this.score = _score;
     }
 }
 

If you want to look at my code, it's this:

 using UnityEngine;
 using Firebase;
 using Firebase.Database;
 using Firebase.Unity.Editor;
 using System;
 
 public class DatabaseManager : MonoBehaviour
 {
     DatabaseReference reference;
     // Start is called before the first frame update
     void Start()
     {
         // Set this before calling into the realtime database.
         FirebaseApp.DefaultInstance.SetEditorDatabaseUrl("https://project-SecretCode.firebaseio.com/");
 
         // Get the root reference location of the database.
         reference = FirebaseDatabase.DefaultInstance.RootReference;
 
     }
 
     public void ButtonLoad()
     {
 
         ReadDataBase();
     }
     //leee toda lavase de daton en el apartado score
     [ContextMenu("ReadDataBase")]
     void ReadDataBase()
     {
         //reference
         FirebaseDatabase.DefaultInstance
        .GetReference("Score")
        // .GetReference("Score").Child("javi")
 
        .GetValueAsync().ContinueWith(task =>
         {
             if (task.IsFaulted)
             {
                 // Handle the error...
             }
             else if (task.IsCompleted)
             {
                 DataSnapshot snapshot = task.Result;
                 //Debug.Log(snapshot.GetRawJsonValue());
 
                 string jsonStr = snapshot.GetRawJsonValue(); //result Json To String
                 Debug.Log(jsonStr);
             }
         });
 
 
     }
 }
 [Serializable]
 public class Points
 {
     public string name;
     public string score;
 
 
 
     public Points(string _name, string _score)
     {
         this.name = _name;
         this.score = _score;
     }
 }
