ShowChatGUI() needs to be called from inside OnGUI so it is drawn on every frame. You can use a boolean setting to enable or disable the chat lobby.

Here is a example I experimented with

 using UnityEngine;
 using System.Collections;
 
 public class lobby : MonoBehaviour {
 
     public bool started;
     public GUISkin gSkin;
 
     public bool showChatLobby; //could as well be private, but like to see things like that in editor while developing
 
     void OnGUI() {
         if (!started) return;
         
         GUI.skin = gSkin;
         ShowChatGUI();
         if(showChatLobby){
             DrawLobbyGUI();
         }
     }
     
     
     public void ShowChatGUI(){
         
         
         if (GUI.Button (new Rect (10,Screen.height - 80,120,120), "Test Chat Button")) 
         {
             if(!showChatLobby){
                 showChatLobby = true;
             } else {
                 showChatLobby = false;
             }
             
 
             
         }
 
     }
     public void DrawLobbyGUI() {
         GUI.Box(new Rect(10,10,150,25), "test text");
     }
 }
