While writing the @choice function, I wrote a script that went over the label using an external script.

But if you move on like this, the choice UI won't disappear.

@hide Can't I make the choice function disappear?

You can hide choice handlers, for example @hide ButtonList should work. To hide specific choices, you can clear the choices using @clearChoice and hide the choice based on a condition (e.g @choice "Choice" if:!HasPlayed()).
