Becoming admin/Giving admin access

Hello. I just purchased a server, and I am fairly new to using Rcon.
I know that in Gmod, When hosting a dedicated server, you can use the adduser <user> Superadmin 1 command to make a user an admin. But that doesnt seem to work on Rust. Is their a certain command to give layers access to admin status? Or does everyone I want to be an admin simply login with rcon.login <password>?

Yeah just tell him your rcon password and thats all

Okay, thank you.
