Statistics on how many images are uploaded via app

[HerziPinki]

Is there any statistics available, how many images are uploaded via the app?

As a single upload triggered by the app can contain many images, we only could count the number or uploads, not the number of images. It's clear, that uploads can be cancelled. I want to get a feeling.

Any idea on how to count basic figures, admin access should be sufficient.
(just a note until now - no action required)

is this frontend or backend functionality?
as a surrogate we have mapbox accesses (counted by mapbox).

we once had an analytic package integrated, witch was discontinued.
