How to set myself as an admin in my game?

I've recently used a template for a battle royale game and i dont know how to set myself as an admin, there are admin commands (when the key ` is pressed), in the code there there are groups for admins, i changed one of the groups to my group and i still can not use the admin commands https://gyazo.com/39d9f3f47591aa486bd6ff2c9fadab3d https://gyazo.com/15d91530f16b133f7b1c18e1fa2cd104
