Rear license plate nut.
 

I've seen a few threads about this, but can't find the one I was looking for again.

When I tried to put my plate on, one of the nuts fell in the bumper. Now, I know I can remove it to get the nut, but I'd rather not. Seems like a lot of work for someone who has never removed something like that before. I looked on the Autozone app for something at least close to what was there, and this is what they had. Will either of these work? Would I have better luck finding a proper nut from Home Depot?
