From Android 11, package visibility is used to prototect user privacy.

Most app is not visible for my app according to:
https://developer.android.com/training/package-visibility

Still some is automatically visible for my app:

But what is the exact meaning of ‘your own app’ in above link?

Same signature? Other components in this app?
