Sapphic horror recs and maybe I'll find what I'm looking for

There are several YT creators I watch, but I'm pretty sure the recommendation originated with Sinead Hannah. It is supposed to be a retelling of an old fable, made sapphic. A woman gets into a relationship with a nun while running and hiding in the woods. I think it was in the same video where she discussed Saint Maud (although I'm not positive)

Can't anyone tell me what it might be called? Or point me to the video?
