Display Json data in unity - json

Question

I want to create scoreboard with Firebase in Unity.
I know how to access data but I have problem with displaying these on screen.
I tried to add user data to list but I'm not sure if this is a good idea or if this will actually work
Here is my code:
public class Scoresmulti : MonoBehaviour
{
//Zliczanie punktów i wyświetlanie wyniku
public static int pointssum = 0;
public Text points;
private string user;
public String scoresboard;
public Array Scores;
public List<USers> scores = new List<USers>();
USers users = new USers();
public static fsSerializer serializer = new fsSerializer();
void Start()
{
//Posttodb();
Debug.Log("wykonano");
Getdata();
}
private void getscore()
{
//display text
}
void Update()
{
points.text = "Poprawne odpowiedzi: " + pointssum;
}
private void Posttodb()
{ user = nazwagracza.Playernick;
if (user != null)
{
USers users = new USers();
RestClient.Put("https://quizgame-inz.firebaseio.com/names/" + user + ".json", users);
}
}
private void Getdata()
{
StringBuilder builder = new StringBuilder();
RestClient.Get("https://quizgame-inz.firebaseio.com/.json").Then(response =>
{
fsData userdata = fsJsonParser.Parse(response.Text);
USers[] users = null;
serializer.TryDeserialize(userdata, ref users);
foreach (var user in users)
{
scores.Add(user);
}
});
}
}
