Despite your suggestion in your prematurely-closed question at https://support.mozilla.org/en-US/questions/1415834 the Android app *STILL* doesn't have the Sync and Save Data option. This is v120.1.1 (you know, well after the Overflow Menu got BROKEN in the desktop version). I have NO idea what device you must be using to suggest scanning from the keyboard, but this phone has no such item. And scanning from the camera complains that I didn't scan from the non-existent option in the app.
