Each organization can have one or more admins. Admins can edit organization or team settings and manage billing.
Click on Members in the organization navigation to see the list of organization members, and toggle admin access on or off:
Switching Admin status to another Member
When an organization has only one Admin, and you wish switch admin status to another user, the current Admin can make the new admin the Organization Admin. The new Admin can then remove admin status from the old Admin.
