ShutdownRequested not working on macOS

[WanderingForLove]

Describe the bug
Hi, I tried to add ShutdownRequested in OnFrameworkInitializationCompleted function, however it does not seem to work.

To Reproduce
Steps to reproduce the behavior:

public override async void OnFrameworkInitializationCompleted()
{
    if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
    {
        ...... // Some code here
        desktop.ShutdownRequested += Desktop_ShutdownRequested;
        ...... // Some code here
        if (!string.IsNullOrWhiteSpace(Global.Settings.Cookie) && !CookieToolkit.IsExpired(Global.Settings.Cookie))
        {
            desktop.MainWindow = Global.PageToolkit.GetMainPage();
        }
        else
        {
            desktop.MainWindow = Global.PageToolkit.GetLoginPage();
        }
    }

    base.OnFrameworkInitializationCompleted();
}

private void Desktop_ShutdownRequested(object sender, ShutdownRequestedEventArgs e)
{
    LogToolkit.Error("Hello World");
}

Expected behavior

LogToolkit.Error("Hello World");

was executed
