I recommend Marc-André Argentino's research on the Com; he's a conspiracy researcher who got his PhD on QAnon. He leans left, if that's a factor for you.
His general overview: https://www.maargentino.com/the-pillars-of-the-com-network/
That piece doesn't get specific at all about Com activities but be aware that some of the manifestos and other material he discusses is quite disturbing.
