This is a helper script to pull cached files on the device (or Emulator). Android 13 and above doesn't let us see the cached files from the Device Explorer. So, this script help us to pull them and look at it whenever needed.

My app stores files under /data/user/0/$app_package_name/files. These are usually JSON files that my app downloads from the back-end.

However, this is not the App private space for saving files like shared preferences. I have created another copy of this function and replaced /data/user/0/$app_package_name/files with /data/data/$app_package_name/shared_prefs.
