OculusGo - can't access files in the persistent data folder.

I have placed some data files in txt or json format in the Application.persistentDataPath folder.
But the Directory.GetFiles() method doesn't bring me any results.
Is it a matter of some settings on the device or publishing settings or manifest.xml file?

 

You dont need manifest permissions, read
