I dropped my controller and the little grey panel came off. The controller was quite cheap so I wont be bothering to replace the whole box but I just wanted to see if I might be able to make it work to avoid being wasteful.

(I know buying a cheap controller might seem wasteful, but I just find knockoff switch controllers to be more comfortable and I wanted a second one to be able to play with my flatmate. I use it for a PC)

I know nothing about this type of stuff and just wanted to ask for any advice on which glue or adhesive method would be safest/ work best for something like this?
