Android - Runtime permission not displaying dialog after user denies it a couple of times

Question

Permissions has changed a lot on Android and the most useful implementation for me, so far has being posted on this question, which uses the ActivityResultContracts.RequestPermission() object and the registerForActivityResult() method.

The code from the link above was implemented in a Fragment as follow:

private lateinit var requestPermissionLauncher: ActivityResultLauncher<String>

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View {
    val contract = ActivityResultContracts.RequestPermission()
    requestPermissionLauncher = registerForActivityResult(contract) { granted ->
        if (granted) {
            // PERMISSION GRANTED CODE
        } else {
            // PERMISSION DENIED CODE
        }
    }
    // ...
}

val permissionResult = ContextCompat.checkSelfPermission(requireContext(), Manifest.permission.POST_NOTIFICATIONS)
if (permissionResult == PackageManager.PERMISSION_GRANTED) {
    // PERMISSION GRANTED CODE
} else {
    requestPermissionLauncher.launch(Manifest.permission.POST_NOTIFICATIONS)
}

Everything is working fine, accept on a scenario where the user declines the runtime permission notification a couple of times. In this scenario, the notification it's not being showed again and I can't figure out what is missing.
