Teams VTC interviews: what do your subjects see?

Hey investigators: for your Teams/VTC interviews what do your subjects see, eg how do you have your home office set up? Do you use a Teams-provided background? Do you simply blur your background? Do you have a a nice real-life backdrop with books and tastefully arranged family photos that would get you a good grade from RoomRater? Do you have any items on your shelf behind you (MAGA hat, selfie with Joe Biden) of a political or religious nature?

I feel like the Venn diagram of “contract DCSA investigators” and “people who know who follow RoomRater on Twitter” has to be a pretty small one so I am interested to read the replies!
