ShouldUseDarkColorsAsync always returns False

public static class ThemeService
{
   public static void InitializeThemeListener()
    {
        var nativeTheme = Electron.NativeTheme;

        nativeTheme.Updated += async () =>
        {
            var isDarkMode = await nativeTheme.ShouldUseDarkColorsAsync();
            Console.WriteLine(isDarkMode
                ? $"OS theme changed. Dark Mode: {isDarkMode}"
                : $"OS theme changed. Light Mode: {isDarkMode}");
        };
    }
}

The listener is triggered appropriately when I change the default theme on macOS Sequoia.
Am I misunderstanding how to check for OS initiated theme changes?
