❔ Laptop Lid Close Event?

Anyone know how I can detect when the laptops lid is closed? This is my code so far but it doesn't work, any help is greatly appreciated

    static void CreateLidCloseEvent()
    {
        // Create a new WMI event query to monitor for changes in the state of the lid
        WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_PowerManagementEvent WHERE EventType = 4");

        // Create a new WMI event watcher to watch for the event
        ManagementEventWatcher watcher = new ManagementEventWatcher(query);

        // Attach an event handler to the watcher
        watcher.EventArrived += new EventArrivedEventHandler(LidClosed);

        watcher.Start();

        Console.WriteLine("Waiting for lid closing event...");
        Console.ReadLine();

        watcher.Stop();
    }

    private static void LidClosed(object sender, EventArrivedEventArgs e)
    {
        Console.WriteLine("Lid closing event detected.");
    }

    static void CreateLidCloseEvent()
    {
        // Create a new WMI event query to monitor for changes in the state of the lid
        WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_PowerManagementEvent WHERE EventType = 4");

        // Create a new WMI event watcher to watch for the event
        ManagementEventWatcher watcher = new ManagementEventWatcher(query);

        // Attach an event handler to the watcher
        watcher.EventArrived += new EventArrivedEventHandler(LidClosed);

        watcher.Start();

        Console.WriteLine("Waiting for lid closing event...");
        Console.ReadLine();

        watcher.Stop();
    }

    private static void LidClosed(object sender, EventArrivedEventArgs e)
    {
        Console.WriteLine("Lid closing event detected.");
    }
