How do I make it so that a script will only activate if a certain team touches it?

So I have a script for a brick, that will only work when a player touches it. However, I only want the script to work if a certain team touches it. I wanted the Prisoners to be the only ones who could use it. (The teams are Prisoners, Guards, and Neutral, if you need that info) I'm not requesting anything, I just wanted to see if someone could tell me how to do it, if they couldn't be bothered to do it themselves.
