WAMR is the utility you were looking for. With one tool you are able to recover text messages and also any media attachment (pictures, videos, voice notes, audio, animated gifs and stickers)!
Now you can also download Statuses! All with one app!

HOW IT WORKS
Messages are encrypted on your device so WAMR can’t access them directly.
The only solution available is to read them from the notifications that you receive and create a message backup based on your notification history.
When WAMR will detect that a message as been deleted, it will immediately show you a notification!

MEDIA MESSAGES
WAMR will also try to save any media attached to the message and if the sender deletes it, you will receive a notification.
The following media types can be recovered: pictures, videos, animated gifs, audio, voice notes, documents, stickers.
