Handle notification open in a uniform way for both iOS and Android

[Aman1706]

I am receiving remote notifications via FCM. One minor issue I have is using the onForeground event to detect notification tap only works for iOS and for Android, I have to use getInitialNotification from the RNFCM package. This function does not work for iOS so I have to conditionally call both functions when handling the notification open event.
I have attached the code snipped below.

  const notificationOpenHandler = async (
    notifMessage:
      | Notification
      | undefined
      | FirebaseMessagingTypes.RemoteMessage
      | null,
  ): Promise<void> => {
    try {
      // checks whether the group id is available or not
      // then open the respective group chat screen
      if (notifMessage?.data?.group_id) {
        navigation.navigate(chatScreen, {
          groupId: String(notifMessage.data.group_id),
        });
      }
    } catch (e) {
      sentryError(
        `Unexpected error occured when opening group ${
          notifMessage?.data?.group_id
        } from notification.
         Error Details: ${(e as Error).message}`,
      );
    }
  };

// handling of notification click
useEffect(() => {
    if (Platform.OS === 'ios') {
      const foregroundEvent = notifee.onForegroundEvent(({type, detail}) => {
        const {notification} = detail;
        if (type === EventType.PRESS) {
          notificationOpenHandler(notification);
        }
      });
      const unsubscribe = notifee.onForegroundEvent(foregroundEvent);
      return unsubscribe();
    } else if (Platform.OS === 'android') {
      // Check more docs here: https://rnfirebase.io/messaging/notifications
      messaging()
        .getInitialNotification()
        .then(notificationOpenHandler)
        .catch(e =>
          sentryError(
            'Unexpected problem occured when opening app from quitted state' +
              e.message,
          ),
        );
      const unsubscribe = messaging().onNotificationOpenedApp(
        notificationOpenHandler,
      );
      return unsubscribe;
    } else {
      return;
    }
  }, []);

Although this works, is there a function which could work for both platforms? Having two separate functions being conditionally called doesn't seem very good in terms of code quality.
Thank you
