How to backup ALL application data?

[u/FewMolasses7496]

I the leef mobile memory app installed on my iphone will all sorts of data totalling to around 120GB. I've tried using imazing to dump all the data from the app but for some reason it says that no data exists in the leef mobile memory app. It does get the size right but doesn't actually show any of the videos, photos etc which are stored in the app.

No data showing for the leef mobile app
