How to condition based on github teams?

[alexInhert]

the example https://github.com/actions/github-script#welcome-a-first-time-contributor shows how to write a message to a first time contributor.
Is it possible to write a message to any contributor except users set in a specific github team?

👋 You could do this by fetching the members of a team and then checking if the creator is in that team.

The List team members API should help get you started.
