The permissions are still not correct. I still see 2 teams with maintainer rights. There should be no other team added to the repo except for admin and triage team. Everyone else should be added as individual user. @ananzh @seanneumann

The below teams are still part of the permission group.

@opensearch-project/opensearch-dashboards-core • 11 members
@opensearch-project/oui • 10 members
