How can you make a zone only one team can enter?

How can you make a zone only one team can enter? I looked at another post about this, but it didn’t give enough info on how to do it.

Um, zones can be entered by anyone, do you mean like wires?

Isn’t there a way to make a zone device that only one team can enter?

If you make teams, that is.

well zones don’t do anything by themselves unless they get provoked. Like through a channel or wire.

Yeah, that is what I meant.

Maybe a barrier?
That could work maybe…
