can't find AirplaneModeSwitch in AutomationElement.RootElement

Hi,

my tool is for enable Airplane mode or disable it.

source is C#, as following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Automation;

namespace Airplane
{
    class Program
    {
        static void Main(string[] args)
        {
            GetDesktopElement();
            //GetFocusedElement();

        }
        public static void GetDesktopElement()
        {
            var NetworkCondition = new PropertyCondition(AutomationElement.AutomationIdProperty, "AirplaneModeSwitch");
            var mainNetwork = AutomationElement.RootElement.FindFirst(TreeScope.Element, NetworkCondition);
            TogglePattern slider = (TogglePattern)mainNetwork.GetCurrentPattern(TogglePattern.Pattern);
            Console.WriteLine(slider.Current.ToggleState);
            slider.Toggle();
            Console.WriteLine(slider.Current.ToggleState);
        }
        public static void GetFocusedElement()
        {
            var NetworkCondition = new PropertyCondition(AutomationElement.AutomationIdProperty, "AirplaneModeSwitch");
            var mainNetwork = AutomationElement.FocusedElement.FindFirst(TreeScope.Element, NetworkCondition);
            TogglePattern slider = (TogglePattern)mainNetwork.GetCurrentPattern(TogglePattern.Pattern);
            Console.WriteLine(slider.Current.ToggleState);
            slider.Toggle();
            Console.WriteLine(slider.Current.ToggleState);
        }
    }
}

i found use GetFocusedElement() worked after execute

rundll32.exe %SystemRoot%\system32\van.dll, RunVAN

but GetDesktopElement() can't work.

due to execute "rundll32.exe %SystemRoot%\system32\van.dll, RunVAN" will open a sidebar, i want skip this step, just fetch the automation UI "airplane mode" direct.Would you help me?
