Organization owners and team maintainers can add repositories to a team, as well as change the team's read, write, and admin access to the repository.
Warning: If you remove a person’s access to a private repository, any of their forks of that private repository are deleted. Local clones of the private repository are retained. If a team's access to a private repository is revoked or a team with access to a private repository is deleted, and team members do not have access to the repository through another team, private forks of the repository will be deleted.
