UV Drop down doesn't exist in my 2.91

I’ve been looking for about half and hour now and googling anything I can but everything I find says “Use the overlay drop down menu” but I don’t have a drop down menu at all. lol

Am I losing it or just missing something totally obvious?

I’m just trying to view UV map stretching and instead my brain is being stretched thin :sob:

I just downloaded 3.0. Whatever. lol
