Guide to Lirp and the Hexagram rituals?

Recently i got interested in the rites of the golden dawn and have been practicing the LBRP and the Middle pillar but i wanted to learn more. How could i do that? its quite hard finding anything about the LIRP and Hexagram rituals.

I´d appreciate a good book recommendation or some yt channel, blog or really just a written guide for the Rituals of the golden dawn

Self-Initiation in the Golden Dawn Tradition or Golden Dawn Magic, both by Chic Cicero.

The Golden Dawn by Israel Regardie.
