Problems with Photon Chat

I'm trying to implement a chat system in my game using photon chat, but simply it doesnt work, idk why, theres no erro messages, theres no warnings there's no logs, it simply dont work, if i use Debug.Log to show message it simply show nothing (the log message shows with empy string). The prefab even is instantiated, here's my code:

 public void OnGetMessages(string channelName, string[] senders, object[] messages)
     {
         /* All public messages are automatically cached in `Dictionary<string, ChatChannel> PublicChannels`.
          * So you don't have to keep track of them.
          * The channel name is the key for `PublicChannels`.
          * In very long or active conversations, you might want to trim each channels history.
          */
 
         foreach (var channel in chatClient.PublicChannels)
         {
             if(channelName == channel.Key)
             {
                 for (int i = 0; i < senders.Length; i++)
                 {
                     GameController.networkController.authManager.database.GetReference("users").Child(senders[i]).GetValueAsync().ContinueWith(t =>
                     {
                         if (t.IsFaulted)
                             Debug.LogError(t.Exception);
                         else if (t.IsCompleted)
                         {
                             DataSnapshot snapshot = t.Result;
                             if (snapshot.Exists)
                                 Instantiate(TextPrefab, chatContent).GetComponent<TextMeshProUGUI>().text =
                                     string.Format("{0} : {1}", snapshot.Child("DisplayName").Value, messages[i]);
                         }
                     });
                 }
                 break;
             }
         }
     }
