Push Notifications Not Working on Android (Intercom SDK with Capacitor)

[shifanpark]

Describe the bug
I am using @capacitor-community/intercom (version 7.0.3) and have encountered
an issue where push notifications are not working on Android.

I can ensure the basic configurations are correctly configured
in below setups

1. google-services.json is correctly placed and configured.
2. Set up the Push Server API key with Firebase Cloud Messaging for APNs authentication key correctly.

To Reproduce
Steps to reproduce the behavior:
Below is the way I used to send the push token to the intercom

Intercom.registerIdentifiedUser({
  userId: userEmail,
  email: userEmail,
}).then(async () => {
  let permStatus = await PushNotifications.checkPermissions();

  if (permStatus.receive === 'prompt') {
    permStatus = await PushNotifications.requestPermissions();
  }

  if (permStatus.receive !== 'granted') {
    throw new Error('User denied permissions!');
  }

  await PushNotifications.register();
  PushNotifications.addListener('registration', (token) => {
    if (token) {
      Intercom.sendPushTokenToIntercom(token);
    }
  });
});

Expected behavior
Push notifications should work on Android after registering the token with Intercom.

Environment (please complete the following information):

• Intercom SDK Version: 15.11.0
• Capacitor Intercom Plugin: 7.0.3
• Push Notifications Plugin: @capacitor/push-notifications
• Android version - 14
