Ceramic Shield Back.

I am trying to use a phone ring on my (naked) iPhone 12 Pro, but I can’t get any to stay put longer than a few days. I know that gorilla glue will keep it on, but what damage will the glue do to the Ceramic Shield, if any? Don’t want a case with a built-in ring (don’t want a case at all—want to enjoy the form factor), so hold those comments please.
