private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
{
        var reply = context.MakeMessage();
        reply.Attachments.Add(GetAudioCard());
        await context.PostAsync(reply);
        context.Wait(MessageReceivedAsync);
}


private static Attachment GetAudioCard()
{
    var audioCard = new AudioCard
    {
        Title = "Havana",
        Subtitle = "Camila Cabello",
        Image = new ThumbnailUrl
        {
            Url = "https://en.wikipedia.org/wiki/Havana_(Camila_Cabello_song)#/media/File:Havana_(featuring_Young_Thug)_(Official_Single_Cover)_by_Camila_Cabello.png"
        },
        Media = new List<MediaUrl>
        {
            new MediaUrl()
            {
                Url = "http://213.32.113.82/music/Now%20Thats%20What%20I%20Call%20Running%20(2018)/CD1/02.%20Camila%20Cabello%20feat.%20Young%20Thug%20-%20Havana.mp3"
            }
        },
        Buttons = new List<CardAction>
        {
            new CardAction()
            {
                Title = "Read More",
                Type = ActionTypes.OpenUrl,
