Hi, I am trying to display a alert window if user denied permissions to use camera in chrome desktop browser so I tried:

ionViewDidLoad() {
    let scanner = new ZXingScannerComponent();
    if (scanner.hasPermission === false) {
      alert(scanner.hasPermission);
    }
  }

But when I clicked deny permission, There is no alert, only a console.log Permission denied.

May I know how can I achieve alert window instead? Thanks
