How do I move text / call a 2d box collider in unity 3d

I just only want to keep the text . I don't want the going button because when I play the scene it takes up most of the scene . I am going to have a box collider surround the text so I am able to touch text and switch scenes here is what I got for code :

 using System.Collections;
 using GooglePlayGames;
 using UnityEngine.SocialPlatforms;
 
 public class lok : MonoBehaviour
 {
 
   public GUISkin skin;
   public int incrementalCount = 5;
 
   //leaderboard strings
   private string leaderboard = "Your unique leaderboard id";
   //achievement strings
   private string achievement = "Your unique achievement id";
   private string incremental = "Your unique achievement id";
 
   // Use this for initialization
   void Start()
   {
     PlayGamesPlatform.Activate();
   }
 
   // Update is called once per frame
   public void OnGUI()
   {
     GUI.skin = skin;
     skin.button.fixedWidth = Screen.width - 25;
     skin.textField.fixedWidth = Screen.width - 25;
     GUILayout.BeginArea(new Rect(0, 0, Screen.width, Screen.height));
 
     GUILayout.BeginVertical("box");
 
     GUILayout.Label("Official Google Play Games Services");
 
     GUILayout.Space(20);
 
     //Share Status
     if (GUILayout.Button("Log In"))
     {
       Social.localUser.Authenticate((bool success) =>
       {
         if (success)
         {
           Debug.Log("You've successfully logged in");
         }
         else
         {
           Debug.Log("Login failed for some reason");
         }
       });
     }
 
     GUILayout.Space(20);
 
     //Achievement
     if (GUILayout.Button("Unlock Achievement"))
     {
       if (Social.localUser.authenticated)
       {
         Social.ReportProgress(achievement, 100.0f, (bool success) =>
         {
           if (success)
           {
             Debug.Log("You've successfully logged in");
           }
           else
           {
             Debug.Log("Login failed for some reason");
           }
         });
       }
     }
 
     GUILayout.Space(20);
 
     //Incremental Achievement
     if (GUILayout.Button("Press " + incrementalCount + "more times to unlock incremental acheivment"))
     {
       if (Social.localUser.authenticated)
       {
         ((PlayGamesPlatform)Social.Active).IncrementAchievement(incremental, 5, (bool success) =>
         {
           //The achievement unlocked successfully
         });
       }
     }
 
     GUILayout.Space(20);
 
     //Leaderboard
     if (GUILayout.Button("Post your 5000 points to the leaderboard"))
     {
       if (Social.localUser.authenticated)
       {
         Social.ReportScore(5000, leaderboard, (bool success) =>
         {
           if (success)
           {
             ((PlayGamesPlatform)Social.Active).ShowLeaderboardUI(leaderboard);
           }
           else
           {
             //Debug.Log("Login failed for some reason");
           }
         });
       }
     }
 
     GUILayout.Space(20);
 
     // Show Leaderboard
     if (GUILayout.Button("Show Leaderboard"))
     {
       Social.ShowLeaderboardUI();
     }
 
     GUILayout.Space(20);
 
     //Show Specific Leaderboard
     if (GUILayout.Button("Show Specific Leaderboard"))
     {
       ((PlayGamesPlatform)Social.Active).ShowLeaderboardUI(leaderboard);
     }
 
     GUILayout.Space(20);
 
     //Show Achievments
     if (GUILayout.Button("Show Achievments"))
     {
       Social.ShowAchievementsUI();
     }
 
     GUILayout.Space(20);
 
     //Sign Out
     if (GUILayout.Button("Sign Out"))
     {
       ((PlayGamesPlatform)Social.Active).SignOut();
     }
 
     GUILayout.EndVertical();
     GUILayout.EndArea();
   }
 }
