Apps reside in main storage. At no time has Android offered a default location anyplace else. I don't want to write a brusque answer here, but let's use what we know so far.

Some, not all versions of Android (google Android Fragmentation) allow you to move an installed app to other storage and apps might allow you to change where they store app data but at no time has any version offered a change to the "location of default apps."

If you wish to go poking around the file system with a file manager, go right ahead but as versions and apps do tend to move items around, unless I own your model I can't do this hunt for you.

My answer here is to address the "HOW" component of your question. Again, as I don't own your model, you have to find this on your model.
