There are 2 main issues related to checking if we have the permission of NotificationListenerService  being granted:

1. It is said that "getEnabledListenerPackages is inherently asynchronous with permission granting, because it's reading from Settings.
"
https://issuetracker.google.com/issues/257072930#comment4

And yet the docs don't even mention anything about it:
https://developer.android.com/reference/kotlin/androidx/core/app/NotificationManagerCompat#getEnabledListenerPackages(android.content.Context)

2. Even if we avoid using it, and we use the documentation of onListenerConnected , I've already shown in another report, that the call to it might be done even when the permission isn't granted at all, as opposed to the docs:
https://issuetracker.google.com/issues/257097402
It's said to be fixed, but Android 13 is still the latest one, and we need a solution that will work for all Android versions.

This means it's not a reliable API and can't be used to check if the permission is truly granted, as opposed to any other permission check which is always reliable.

So, please :
1. Update the documentation and warn about relying on these functions.
2. Deprecate getEnabledListenerPackages as it's not a reliable way to check if the app has the permission, even when you reached onListenerConnected
3. Offer an alternative way to check if the permission is granted, that will work on all Android versions from API 18 (the one that NotificationListenerService was available).
4. Off a callback/Intent/LiveData so that we could listen to it to check for updates about the permission being granted.
