Admins have the ability to set security roles for staff profiles. The default security groups are System Admin, HR Staff, Staff, and USCIS.
Navigate to "Configure" > select "Staff" > click "Edit" next to the employee's account > On the next page select the System Admin security group from the "Security Level" drop-down > Click "Save" to assign the Admin security group to an employee.
