How to give temporary admin rights?

Prompt what plugin is able to help me give admin rights by SteamID.
To the right were not complete, high kick and ban players.

I may be wrong, but with Rust Essentials permissions and ranks system you could give access to the /kick command to a select group of players, without giving the RCON password. But to my knowledge if that works, you would have to reboot the game service to remove their access. Iv had issues with the /reload command
