As a scrum master, what am I to my team?

Edit: I seem to have written my post in a way that focused on the wrong thing. This is simply about terminology.

If I say “I’m a developer, and the team I’m a part of does foo” then you’d understand my position.

If I’m a scrum master (who is a scrum master for two teams), I might say “one of the teams that I am a scrum master of”, but I was wondering whether there was a way to say that in a less clunky way?

Am I … scrum mastering them? That’s not a word, I think.

So what do you call “the overall thing” that a scrum master does? What’s the established industry term?
