How can NotificationListenerService used in MAUI?

I'm trying to listen to notifications of other apps and for that purpose I tried to utilize NotificationListenerService.

I have seen several examples from Xamarin, but nothing seems to work.

So how is it done in MAUI? How is the NotificationListenerService accessed?

Well, I had already declared the service in the Android manifest file.

<service android:name=".NotificationListener"
android:label="@string/NotificationListener"
android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
	<intent-filter>
		<action android:name="android.service.notification.NotificationListenerService" />
	</intent-filter>
</service>

Yet when I try to extend the class:

public class NLService : NotificationListenerService
{
    
}

I get the following error:

CS0246: The type or namespace name could not be found (are you missing a using directive or an assembly reference?)
