Project Zomboid: Help with Admin rank?

[darknano]

This is the first time I've started with a Project Zomboid server and I've had server experience before, just not with GameServers. Anyway, I'm trying to figure out how to set certain admin privileges for in-game users but I can't seem to figure out how? I've checked (most of) the files on my FTP for the server and can't seem to find anything. Along with that, from my previous server experience there was a real-time console that would allow me to do certain things in the server real-time and I'm not sure how to access that either.

I'd love some help, thanks!
