Download location of Aurora Store?

Working on an Android 6 (Stock ROM) phone, which has only internal storage (no external SD card), and is not rooted. Aurora Store is installed and updated on this phone via F-droid. Aurora Store has a "Downloads" choice in its "hamburger" menu, where I see something like this: So, clearly some .apk's have been downloaded - the question is, where? I have checked the following locations: * /sdcard/Aurora/ - there are some random .apk's there, but not the two on the screenshot * /sdcard/Download/ - again, some random .apk's there, but not the two on the screenshot With a bit of find, I also found the following location - but unfortunately, it turns out completely empty in adb shell:

$ ./adb shell
shell@DDDDD:/ $ ls -la /sdcard/Android/data/com.aurora.store/files/Downloads/
shell@DDDDD:/ $

My guess is, the .apk's Aurora downloaded are actually here - but I cannot access/see them, because I'd need root for that, and this phone is not rooted. Could anyone confirm, what should be the default downloads directory/location for Aurora Store, on an unrooted phone with only internal storage - and whether root is needed to access these files?
