There should be a channel named roles or introduction or something, and then if you scroll to the top of those channels there should be messages with reactions, and the message should tell you which reaction to click

Here let me grab an example

something like this

Ok wait I’ll screen shot and send to u as well

Okay!

So I should pick one of those reactions??

Yes!

Ahhh thank you

That will give you a role in your server profile

Of course!
