txAdmin only in duty

Hello.
How can I do it so that I can use the TxAdmin ID system with my own command and put it in my staff script so that it can only be used on duty.
Also, how can I do it that txAdmin can only be opened in duty. I’ve seen it on many servers and I can’t do it by myself.

May be able to tweak your on-duty script to put your off-duty staff into a different group. They would only be placed in the group that has access to all the toys when they are on duty.
