How do I change the group ranks ingame?

I'm working on a little game for my group members to choose their rank and was wondering how I could do this. I don't actually know anything about scripting, so sharing some code for this would help.

This would actually require a proxy. I recommend you self-host a proxy for this, but RPRXY should work.

First, you'll probably need good knowledge of Roblox Group API endpoints. Also, you'll need to figure out how to authorize as your bot. I can't provide much example code now, but it'll probably take a while anyway.
