How to stop the bolt catch from rattling?

[Pseudotectonic]

It's a cosmetic part I know but it is just rattling around literally held in place by the upper and lower receiver

What is the most solid way of fixing it in place so it doesn't rattle around?

I ended up using some 3M VHB tape, seems to stick quite well, time will tell if it holds up
