Turns out the lens DOES pry out, from the center back of the lens (away from the switch) you can put a pry tool/flathead in and push it out
This is what it looks like with the lens cover off. You see the very subtle indent on the back middle where you can slide something in, but the clips you see are at each end of the back side that need to pop outThat makes good sense. Do you have any pictures showing this? Like, what does it look like without the cover?
