Hints that can't be undone

I have a geometry graph with a geometric puzzle.
I created a button inside the graph that gives you some graphical hints each time you press it.
I would like that the student/user couldn’t undo the hints after he pressed the button.
Is there a way to do that?
Maybe creating an action button so that I can capture the history of some values …

Ok, sorry, the action button just works … and no need to capture the history of anything because the pressCount can’t be undone.
