Let me help you with a few pictures of the backside, because I have a spare pass side glass (because #partshoarding and #2024istheend).
There are 8 hook style plastic clips in that black inner ring that clip onto the base, and indeed they should come off by exerting an even pulling force outward. I marked them up in the photos in red, hope you can get a usable view.
I'm sure there is a tool that grabs the glass on both the bottom and the top to be able hold it steady while pulling, you might want to figure out a makeshift mirror glass puller... that said, the glass is thick and strong, and so is the plastic retention ring, at least judging by its look and thickness, hopefully you can get this done without any damage.
Good luck
