@OZBERG Please make your own post in the future. Because your question is sort of related, I will answer it here.
There is no trash bin for notifications. There is, however, a notification history. Settings/notifications/advanced settings/notification history. Unfortunately, it just shows you the beginning of the notification text, not the whole thing (unless it's very short). If you download Good Lock and the Notistar module, I believe you can choose to save the complete notifications for a period of time you set.
