No mouse cursor in Steam game with Logitech K400r

Post #1 requires everything including AME to already be installed and configured. It just has a single launch option and doesn’t even tell you where that option is supposed to go. That means it assumes I already know how to do all of that. I don’t and that is why I’m trying to find help with installation. #2 and #3 are not comprehensive installation instructions, they again assume that I already know how to do that. The only step by step installation instructions that I can find that are for Linux are in post #6 but as I put into my very first post, it doesn’t work and there is some output that I can’t make heads nor tales of. The base game installs through Steam and I can start it up. It has no mouse so it just sits there at the main menu unable to do anything other than play the introduction music. I’m really starting to feel like I’m being trolled here.
