You don't have to, it's just a suggestion, you can also try to resolve it on your own with the help of Google
Is it /data/data/com.example.rec?
Not /emulated/0/Android/data/com.example.rec - this one is indeed empty
The problem is that shizuku doesn't grant all superuser privileges, hence in my case ZArchiver could get inside /data/data, but then I see "access denied"
So access it via PC with adb is the only viable option
