Why is AngularFireMessaging requestPermission Not Working on Cordova Android?

I'm developing an Ionic Cordova app and have implemented the @angular/fire/compat/messaging plugin.

I use the following code:

TYPESCRIPTCopied
requestPermission() {
    console.log('requestPermission()');
    this.afMessaging.requestPermission
      .subscribe(
        {
          next: (v) => console.log(v),
          error: (e) => console.error(e),
          complete: () => console.info('complete')
        }
      );
}

When running the app using ionic serve, the code works as expected by hitting the next observable and granting permission. However, after compiling the app into an APK and running it on Android, the code only logs "complete" without hitting next (with either a denied or granted response) or throwing an error. Notifications can be enabled manually, but it doesn't affect the result. The same behavior occurs for all afMessaging functions, such as getToken or requestToken.

The firebase-messaging-sw.js is registered successfully on mobile, so I assume that everything else is set up properly since it works in the browser.

Here is my AndroidManifest.xml file:

I’d appreciate any insights or solutions to get AngularFireMessaging working properly on Android within the Cordova environment.
