When a user tries to login to a store where they have no access permission, the login request is presented in a queue of pending requests. The manager clicks the approval button to grant the user access for unlimited time. 

The completed request can be edited to grant access for a specific time or to cancel the permission.

The permission ends on the selected date at 00:00 (midnight).
