(Ionic 4) Can't receive notification with firebaseX when app is in foreground

Question

I have searched for this problem, but nothing works for me. I have try to had the following data in the data content (when server call url to send notification) [notification_foreground] => true [tap] => true

the code to subscribre to the message...

this.firebase.onMessageReceived().subscribe(notification => {
            console.log('NOTIFICATION !!!!');
            console.log(notification);
            alert( JSON.stringify(notification) );
            if (notification['tap']) {
                this.navCtrl.navigateRoot('/test');
            } else {
                alert( JSON.stringify(notification) );
            }
        });

When the app is in the background, I receive the notification and when I tap on it, I have the alert message and console log.

But when the app is in the foreground, nothing is displayed.

Thanks for your help.

With --prod it seem to work without doing nothing else... it's in debug mode that is not working
