Make button disappear, but show label.

I am trying to click on a button, make the button disappear, then show a label in a different location. I can get the label to show up but I can't make the button disappear without making the label disappear as well. I'm using c# and new to scripting so any help is greatly appreciated!

     private bool andrewGreen_Drafted = true;
      private bool player_Drafted = false;
     
     void OnGUI(){ 
         
              if(andrewGreen_Drafted){
                 if(GUI.Button(new Rect(50,50,100,30),Andrew_Green)){
                     player_Drafted = true;
                 }
                 if(player_Drafted){
                     ShowLabel();
                 }
             }
                 
   }
         
         void ShowLabel(){
             GUI.Label(new Rect(Screen.width/2,Screen.height/2,100,30),Andrew_Green);
         
         }
