question

Hey , I am trying to display my username that my player created when they register/login in the game , but I'm very confuse how to do it. I look over the documentation but still I don't know how I can do it. This is the script I am using and I am using Photon too. I was thinking to create this game object "displayName" to the player but I don't know how to make it work with this script that I have..

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using PlayFab;
using PlayFab.ClientModels;
using UnityEngine.UI;
using Photon.Pun;
using Photon.Realtime;
using System;


public class PlayFabAuth : MonoBehaviour
{
    public MPManager mp;


    public InputField user;
    public InputField pass;
    public InputField email;
    public Text message;
    
    


    public bool IsAuthenticated = false;
    LoginWithPlayFabRequest loginRequest;
    // Start is called before the first frame update
    void Start()
    {
        PlayFabSettings.TitleId = "D36F6";
       


        email.gameObject.SetActive(false);
    }


    // Update is called once per frame
    public void Login()
    {        
        loginRequest = new LoginWithPlayFabRequest();
        loginRequest.Username = user.text;
        loginRequest.Password = pass.text;


        PlayFabClientAPI.LoginWithPlayFab(loginRequest, result => {
            
            IsAuthenticated = true;
            mp.ConnectToMaster();
            message.text = "Welcome " + user.text + ", Conecting..";
            Debug.Log("You are now logged in");
            
            


        }, error =>
        {
            
            IsAuthenticated = false;
            message.text = "Failed to login[" + error.ErrorMessage + "]";
            email.gameObject.SetActive(true);
            Debug.Log(error.ErrorMessage);
        }, null);
}
    public void Register(){
        RegisterPlayFabUserRequest request= new RegisterPlayFabUserRequest();
        request.Email = email.text;
        request.Username = user.text;
        request.Password = pass.text;
        








        PlayFabClientAPI.RegisterPlayFabUser(request, result => {
            message.text = "Your account has been created";


        }, error =>
         {


             message.text = "Failed to create your account[" + error.ErrorMessage +"]";
         });
    }
   


}
