Control who can add Google+ users directly

As a G Suite administrator, you can control who can add users and groups to Google+ communities directly (without sending an invitation). You can allow all community owners and moderators to add users directly. Or, you can use the batch-add privilege to allow only specific admins to add users or groups directly.

To add or be added, the user must be in the domain or organization that has Google+ and Groups for Business turned on. You don't have to be a member of the group to add it to the community. For more information on adding Google Groups to communities, see Moderate a Community: Details about groups.
