Multiplayer Server Admin Panel

Hey there guys! So, I have a bit of a dilemma! Any help at all would be greatly appreciated.

I’m trying to create a panel for Server Administrators on “Official” servers for a multiplayer game. I’m having trouble making the widget available for only certain people, however. I was wondering if there was a way to make the widget blacklisted from all players with the exception of certain Steam 64IDs.

This panel is able to kick and ban players. So, it’s imperative that only certain people have access to the panel

Again, thank you in advance!
