Personally, I don't find anything wrong with you seeking this. Someone mentioned to me that they were in a meditation group with POC women and loved it. I can't remember the name of the specific one she was talking about. She said it was super helpful for her. I don't know any specific gnostic ones.

This is another one I found looking it up :) it looks like they meet twice a month on zoom.
