odd question
why would you want to reinvite the manager as a manager ?
unless you mean office manager vs groove workspace manager.
that would imply that you have a workspace that has no manager
bad - you get a warning about this.
now unless participants were given full right
there is no way a participant can change another's persons role
only a workspace manager can do this. the set roles operation is disabled.
best to create new workspace - make a duplicate - the person who does this
becomes the new manager of the new space - rename and then reinvite everyone
as desired.
