Ren'Py Adding hide GUI function to Android version?

[lawfullame]

I'm trying to create an Android version of my VN using the standard tools that are part of Ren'Py. That version works, but there is no way to hide the GUI (Equialent of H key on PC) , at least I didn't find it.

What is the easiest way to add hide GUI functionality to Android version? I prefer a way that does not affect the GUI of the PC version.

And what is the way that most players expect in the Android version?

Edit:
I've already found that the easiest is:
textbutton _("Hide") action HideInterface()
In screens.rpy in the section
screen quick_menu():
variant "touch"

But is this the way players want it, or should I use some other way?

DarkAssassin has done this in his port of the game Betrayed, not sure of the detail.
