Obb folder empty even though I can see inside data folder

Question

I looked through everything I could find but I couldn't find a specific answer to this, sorry. I'm using a Samsung phone running android 13 - it isn't rooted and I can't risk rooting it. Both by using a computer through USB and through the AOSP Files app, I can see files inside the android/data folder, but inside the android/obb folder is appearing to be empty.

This seems strange, firstly as: I read that obb folders are only created when an app needs them, so I'm not sure why it would create them and then leave it empty. And secondly, because I would think there are other files inside these apps that are not showing up within the data folders, as some of the apps are quite big and there aren't files corresponding to certain things that seem to happen too quickly to be downloaded as they're needed - as well as, with how spotty the internet I use is, I would expect to have seen more connection errors as the game tried to access them if they were being downloaded each time.

Do I just not have the right permission to look in the obb folder, even though I can see in the data folder? And if so, is there a way to look inside it without root? For reference, I use a Windows computer. Thanks for any help you can give.

Edit: The file manager linked in this Reddit post about accessing the /data and /obb folders in Android 13 can apparently allow the user to access folders through launching the file manager as if it was within the app the folders belong to. However, even through this, the /obb folder appears to be empty on my phone.

The /obb folder is also empty in the com.sec.android.app.samsungapps app - could anyone with root access who also has that app look inside the /obb folder and confirm whether it is indeed simply empty, or whether I still cannot access it?

If it is truly empty, is there anywhere else that the data from a large app (.eg saved games, animations, character images - all things which I would think would be within the app itself due to fast loading speeds and the lack of connection errors, but are not appearing within the /data folder) might be stored that I am unable to find?

Edit 2: I've been looking into various ADB and ADB shell commands following this list of commands on Github. Is the adb shell pm grant <package name> <permission> only for things like giving permission to apps to use the camera? Or is there a way (not necessarily with this command) to use ADB to change things like read/copy permission? I have seen posts up until fairly recently say that you can still access data and obb through a PC, but they often don't mention how.
