Acces the "Management" module and select the "Staff Managament" sub-category . In the central part you will see all the administrators and educators that exist at the moment in the kindergarten and information about them. At the top, you'll notice a submenu with two options, "User list" and "Roles". Make sure you are on the user list and then click on the green "Add New User" button, located at the top right of the screen.
This action will open another screen where the manager information will have to be entered, but not before ensuring that under "Role Name", "Manager" is selected.
After entering the data, press the "Save" button, and an e-mail will be sent to the specified email address to activate the account.
