On my tests, "clue-admin addmanager" create a new manager user that
can create new projects and manage all others.
If you first create the user and after create your projects, manager
permission will be added to each new project.
But, if you fisrt create a new project and after that create new user
with "clue-admin addmanager", manager permissions is not add to
existng projects.
IMOH this use case try to let existing projects not to be accessible
to all "admin" users with "manager" permissions, o even disable entire
access.
