How to rotate iPhone 12 upside down

Its stupid the way it is and not being able to rotate the Home Screen upside down.

On my desk [just about every other office desk I've seen all the chords are plugged in on the floor at the back of the desk and come up from the back of the desk].

So when I have the phone sitting on my desk charging the cord has to come around from the top of the phone to the bottom of the phone where it's plugged in it gets in the way. If I could just rotate the phone upside down so the charging cord effectively is at the top of the phone it would sit so much nicer on the desk.... this is a stupid Apple thing and I used to be able to rotate it.
