(UWP)如何在ContentDialog中包含按钮启用前的延迟？

private async void ShowContentDialog()
{
    // 创建ContentDialog实例
    ContentDialog dialog = new ContentDialog();
    dialog.Title = "提示";
    dialog.Content = "确定要执行操作吗？";

    // 创建按钮
    Button confirmButton = new Button();
    confirmButton.Content = "确定";
    confirmButton.Click += ConfirmButton_Click;

    // 将按钮添加到ContentDialog的按钮集合中
    dialog.PrimaryButton = confirmButton;

    // 禁用按钮
    confirmButton.IsEnabled = false;

    // 延迟1秒
    await Task.Delay(1000);

    // 启用按钮
    confirmButton.IsEnabled = true;

    // 显示ContentDialog
    await dialog.ShowAsync();
}

private void ConfirmButton_Click(object sender, RoutedEventArgs e)
{
    // 处理按钮点击事件
    // ...
}
