I somehow found a post on the blog with the initiation rite, even though, if you try to open a hyperlinks on BALG that leads to this blog entry, it will say that it is deleted
https://codexastarte.substack.com/p/invocation-of-the-angels-of-omnipotence?s=r. The author talks about their experience and in the end doesn’t do the initiation? Or more like the angels say that he himself doesn’t understand what is initiation and that he uses it as a buzzword. So if you’re gonna do it, understand what you’re asking for.
I haven’t done it, maybe the author uploaded a changed version, @Veil can you please skim over it if it is the same?
