End scrollview c#

Hello I have a scrollview box at the start of my game that explains to the user the objective of the game. I want to add a button to it that will remove it once clicked on ?

well you can draw a button after scrollview.

boolean showScrollview;

if(showScrollview)
{
   GUI.beginscrollview()
   ....
   GUI.endscrollview()
}

if(button)
{
   showscrollview = false;
}
