How do I find files of my running Delphi Rio app on Android Galaxy Tab S6 device

Using Delphi 10.3.2 Enterprise I ha,ve had little difficulty deploying a FMX app to Android 9 after success on a Windows tablet.

However, I'd like to know how to find the files of the running app, partly because I'd like to sideload some files (not using Google Play during development) and I cannot even see them.  I can interrogate GetHomePath and GetDocumentsPath and I see in Deployment manager their Remote Path values.  I'm assuming Delphi handles the slash/backslash issues and that's why the app runs at all.  I don't even see the "data" folder that is referenced in a lot of on-line guidance.

Using Window's File Explorer, the data folder is still inviisble.

Or am I missing the boat completely and things like FileExists don't actually work in Android?

In any case, I'd still like to be able to browse to the app's files.
