Disable button when show an overlay

[SIDLatam]

I’ve got an overlay that shows when I press a button, but it’s background is semitransparent, so we can see the rest of the buttons underneath. How can I make those buttons not clickabled when I’m interacting with the things in my overlay?
look
this is the button i press at the begginning

This is the overlay, with it’s own buttons. But we still can see the other buttons underneath, and I want them disabled when the overlay is open.

PLZ HELP
