How can I see what teams & repositories I maintain?

I am in a large organization with many repositories. I am the maintainer of several teams and several repositories.

I want to do a “health checkup” and make sure that I maintain everything that I should and nothing that I shouldn’t.

I want to then follow up with all of them that I maintain and instill best practices within them.

Two questions:

  1. Mostly, I want to know how I can list all of the teams of which I am the maintainer. Same thing for repos.
  2. Added benefit, is there any “batch action” mechanism I can do across all the repos that I maintain? As a specific example, I want to allow only squash commits on PR merges. I will need to keep iterating on this across all repos, unless there is a means to perform batch actions.
