Container Variable: notification_type
This specifies the method that is used to send notifications. Currently, there are three options available 'Prowl', 'Pushbullet' and 'Telegram'. When the two factor authentication cookie is within 7 days (default) of expiry, a notification will be sent upon synchronization. No more than a single notification will be sent within a 24 hour period unless the container is restarted. This does not include the notification that is sent each time the container is started
