To go to employee permissions, go in the left menu to club employees employees list and in the last column, next to the employee, click on "permissions". You can also delete an employee from here by clicking on the "delete" option in the menu.
After clicking on permissions, you will be taken to a page where you can see all possible management modules. By checking the next checkboxes you will give the user permissions to the modules. Please note that some of the modules are crucial for the system and the data contained in them, so think carefully about who you give access to the key modules. Removing certain elements in the system is irreversible!
