Thank you! I actually found these later on. I forked the repo and added my own versions to get this functioning with Roblox, which included the override for avatars. Which I believe just uses DiscourseConnect avatar override so people can’t change it.
One thing I wish though is that roblox does not provide a email on OAuth so I sadly need to have them signup with a email. but thats a non issue for yall haha.
