Does anyone know how I'm suppose to open this?

I believe this is the vent to my plumbing but I’ve never seen a cap like this. Any ideas?
These have a spring loaded flap in the center that lets out sewage if there's a blockage downstream. Lets it out in the yard instead of your house.
As for opening, I use channel locks opened up all the way wide on two of the adjacent lugs and turn left.

Yes that’s exactly what it looked like when I pulled it out!
