CreateProfileHandler is created only when chrome://settings page is opened.

I assume you want this for all new users that never had this option set?

How do you distinguish between users that have already signed in on Chrome OS
and new users?

       CreateShortcutAndShowSuccess(create_shortcut, desktop_type, profile);
       break;
     }
