The installation procedure is a little tedious: you must copy the script's text and paste it into a user script manager.
I've submitted a pull request to change the suffix to.user.js so that the user script manager can detect the script automatically
One caveat is that some moderator actions are directly linked to SO instead of the team, and then an admin will have to manually copypaste the /c/<teamname> part to perform that action. For example, the link in the screenshot below doesn't work. Note that 20 is the user ID of the user in question.
