What is this part? Where does it go?

My friend tried to fix my broken screen but screwed it up (now I have a white screen). When I took the phone back apart, I found this square black rubber piece behind the rear camera that I don't see on any takedown walk-throughs.
It was sitting freely behind the rear camera on top of the opening on the faceplate.
It is a square, black piece of very thin rubber.
On one side of the piece, it has an edge/ lip that goes along two adjacent sides and another very tiny edge that is only on the corner of the opposite side.
It's about 1cm x 1cm.
I am following iFixit's guide for this takedown and reassemble, but also have searched many other troubleshooting guides, parts stores, and concurrently watching several youtube how-to videos and I don't see this piece anywhere. Does anyone know what it is and where it goes? I suspect it came off another piece and my colleague just put it behind the rear camera because it seemed to fit, but any help identifying it and putting it where it belongs would be greatly appreciated.
Is this a good question?
