interesting, thanks for the tip! do you happen to know the name of the socket type or the specific type of nut, aka what I'd search for?

so that was the first thing I tried after giving up on the hinge covers, but the pliers just pretty much tore up the plastic of one of the nuts instead of turning it. image here: https://imgur.com/a/UDVSjVU

maybe I need to try different pliers or apply less force? thank you!
