I'm quite certain that without Root, you can't access the actual data.
With Solid Explorer, you can *see* the folders, but when you click on the file, you'll get "empty".
It'll be the same regardless of what file explorer you use. Android 11 is designed to do exactly this as part of it's "enhanced" security.
It's not something that most people would need to access normally, but having access would allow someone to share apks of downloaded apps for example, which brings up "why do you want to share app apks"? Generally that's something that isn't "above board".
