Why aren’t my commands working?

Why aren’t my command working in the f8 menu… says access denied . I don’t get it

What command are you trying to use?

Add these to your server.cfg

add_ace group.admin command allow
add_ace group.admin command.quit deny
add_principal identifier.steam:000000000000000 group.admin

And replace 000000000000000 with your steam hex ID.
