If your WebView app is integrated with Firebase and correctly set up to receive push notifications via Firebase Cloud Messaging (FCM), then any notification sent to Firebase by the WordPress plugin should be forwarded to your WebView app.
However, there are a few key things you need to ensure for the system to work correctly:
Proper FCM Integration in your WebView app: Ensure you’ve implemented all necessary codes and settings for FCM in your WebView application.
Permissions and Access: Make sure your app has the appropriate permissions to receive notifications. On iOS, this often involves asking permission from the user.
Device Tokens: Your WebView application should correctly register and update FCM device tokens to ensure notifications are delivered correctly.
Testing: Before relying on this system in production, it’s advisable to conduct thorough testing to ensure everything works as intended.
If all these steps are set up correctly, notifications should appear in your WebView apps.
