* If a previous notification was sent with the same @id, it will be
* replaced with @notification and shown again as if it was a new
* notification. This works even for notifications sent from a previous
* notification. If the flag [flags@Gio.NotificationDisplayHintFlags.UPDATE] is set
* on @notification via g_notification_set_display_hint() the
* notification will be updated instead of replaced
* if a notification with the same ID exists already
* otherwise a new one is created. When updating a notification
* no sound is played and the banner isn't shown again.
* This works even for notifications sent from a previous
* execution of the application, as long as @id is the same string.
*
* @id may be `NULL`, but it is impossible to replace or withdraw
