Maybe a different tack would be to create a new level of staff membership instead?
Admin > Moderator > Team
They could still qualify as ‘staff’ but not show up on the ‘about’ page
I’ve had other occasions where it would be handy to have the ability to tag other employees in conversations even if they are not following most activity in the community, (e.g. raise to the product team for relevant feedback) but did not want to make them moderators for the other privileges
