'Android 12 Exported True not showing notifications in the notification bar

I had to modify my app for Android 12. The app now runs and notifications come but only within the app itself, prior to this they would be in the notification bar. I fixed areas where it needed the android:exported="true" so it would launch on Android 12. But I'm not getting notifications in the notification bar. Could someone help me point out where I've not added the exported rule or if theres something else I need to do ?

Solution 1:[1]

In your FirebaseMessagingServiceIns / MESSAGING_EVENT section, change the exported value to false

    <service android:name="com.spliceystudios.apps.esf.push_notification_firebase.FirebaseMessagingServiceIns"
        android:exported="false">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

and it'll match the guidelines on the Firebase website https://firebase.google.com/docs/cloud-messaging/android/client
