In the „Management” Module you'll have to select the „Staff Management” subcategory. In the middle are all the current members displayed along with their credentials. In the upper right side there is a green button named „Add New User”.
Once you click on it, a page will pop up with fields you'll need to fill in the specifications for the new member. Before entering the name, e-mail, picture, etc. you are required to select the role of the new member. The scroll down bar gives you the different roles in the school to choose out of. Select Manager and the page will adapt and you register the new manager.
