Alert Scrollbar - Ionic

Good Afternoon

I would like to know how to shoot the alert scrollbar presentConfirm () {     let alert = this.alertCtrl.create ({       title: 'Exiting the Application'       message: 'Are you sure you want to exit? ',

  buttons: [
    {
      text: 'CANCELAR',
      role: 'CANCELAR',
      handler: () => {
        console.log('Cancel clicked');
      }
    },
    {
      text: 'SIM',
      handler: () => {
        this.navCtrl.push(HomePage);
      }
    }
  ]
});
alert.present();

}
