Working with Ningizhida?

Hello everyone! This is my first post here but I have been doing magick for roughly a year and a half now and have made awesome changes in my life and begun to slowly get better at this just recently due to Azazel’s help. I feel pulled to work with Ningizhida and I can’t really find any resources outside of historical texts, Simon’s Necronomicon, and Michael Ford (whom I dislike for my own reasons). How would I go about evoking this entity? Has anyone here evoked Ningizhida? Thanks in advance!

I think EA did a live ritual calling the underworld deity down on his YT, try looking at that. Might give you some pointers, otherwise, get a Sumerian Lexicon for deities and look through that.
