* Solution Found*
Hello everyone. I wanted to let you all know that I found a solution to my brilliant discord integration with IPS 4.5 and I'll tell everyone how I did it in case other people have similar issues.
I started with a fresh discord server - no roles, no bots, no members, not a single thing but the bare fresh install.
I then enabled Brilliant Discord through my IPS and followed the configurations. Set the oauth2 callback, use the secret token, and finish step by step prompted integration through my community application.
Once the integration was completed, I viewed my server as my bot (server settings, roles, selected my bot and clicked view server as role).
While I was viewing my server as my bot, I created the appropriate roles that I wanted, all of the rooms I wanted, and assigned them as private or public as needed.
When I went back to my community, i made sure each member group was edited and assigned the appropriate role in the discord settings.
Using my test account "rando," i was able to connect to my server and all my roles were correct with permissions into correct rooms.
This may have been a long way of doing it, but it did work.
