Pain staking removal using a plastic pry tool on the tabs at 4 positions on the inner edge behind the thick outer rim I'm afraid. You can see one at 12 o'clock on your middle picture.
The vents are the same as this. I changed two of mine in the summer and it took me an hour to get one out. In the end I wrapped heavy duty fishing twine round the vent (in your case the auto switch) a couple of times behind the outer visible lip, then using a piece of plastic (the trim tool) I twisted it round and round into a Spanish windlass which pressed all 4 tabs quite a bit and that made the second vent easier to remove using a second pry tool.
Still very awkward.
You can see the tabs here:

Windlass works something like this:
