How do I remove the oatey Caspers drain in my shower pan for repair, when it looks different from typical Oatey drains?

How can I remove this drain? I need to fix some rotted wood under the shower pan, but I’m having trouble figuring it out. The instructions I found for Oatey drains all talk about a “castle” type with an adapter to unscrew, but this one looks different. It says “Oatey Casper’s” on the drain and I’m stumped. Sorry about the grossness of the drain, the bathroom is under construction and I’ve been using it as a trash bag holder.
– update – I think I found the castle nut, but the pipe is in the way… I’m going to try using my Dremel to cut it down a bit.
There’s a rubber stopper wedged between the pipe and the flange, likely hammered in. It might be tricky to remove without causing damage.
Do you happen to have a link I could check out? Or maybe replace it if I do end up destroying it?

Drill carefully into the rubber seal with a 3\16th bit, making about 6 to 8 holes. Make sure not to puncture the bottom, aim for about 1.5 inches deep. Use a hook tool to loosen it. If you accidentally go through, you’ll need to replace the assembly, but it’s a simple process. You can also try using a hole saw, just be cautious not to damage the assembly. Take your time. There are plenty of instructional videos on YouTube. I’ve personally removed hundreds of the Oatey drains.
There should be 2 notches on the inner ring; look for a spanner wrench that aligns with the notches and turn it counterclockwise. After removing the compression nut, the pan and the rest of the drain should come off easily.
If you’re able to reach the piping under the shower, wouldn’t cutting it be the simplest solution? It’s like working with tinker toy PVC pieces. That’s what I would do first, since I’m not familiar with drain flange anatomy or the tools professionals use.
This suggestion might be useful.
