Open differents pages ionic 3 with push notifications

Ionic Framework ionic-v3
1

I need help, I am trying to open different pages of my application in ionic3, I can do it for a specific page, but I want to differentiate the type of notification, example if the notification is of the message type, my message page is opened and if it is another type of notification will open a different page.

 pushObject.on('notification').subscribe((notification: any) => {
        this.nav.push(PushNotification); //here open specific page, but I need to open not only a specific page but several pages.
        if (notification.additionalData.foreground) {
            let youralert = this.alertCtrl.create({
                title: 'New Push notification',
                message: notification.message,
            });
            youralert.present();

        }
    });```
