bots - ボットを使用して Skype で複数のビデオを表示したい場合の問題を解決する方法

Question

私はBotFrameworkを使用してボットプロジェクトに取り組んでおり、ボットに表示するためにいくつかのビデオを使用しています。ここで問題は、ローカルでビデオを表示しているときに正常に機能し、Skypeに構成しているときにビデオが1つしか表示されないことですスカイプで。

コードは次のようになります。

private async void TrailersList(IDialogContext context, Activity message)
{
        Activity replyToConversation = message.CreateReply("Welcome to **MyApp**." + "(Hi)");
        replyToConversation.Recipient = message.From;
        replyToConversation.Type = "message";
        replyToConversation.Attachments = new List<Attachment>();
        Dictionary<string, string> cardContentList = new Dictionary<string, string>();
        cardContentList.Add("Jason Bourne", "");
        cardContentList.Add("The Land", "");
        cardContentList.Add("Yoga Hosers", "");
        foreach (KeyValuePair<string, string> cardContent in cardContentList)
        {
            if (cardContent.Key == "Jason Bourne")
            {
                replyToConversation.Attachments.Add(new Attachment()
                {
                                                                ContentUrl= "https://ce5qxa-bn1306.files.1drv.com/y3m9N1SkzBRmwSTd_OZgBWhsAVBzHi5ij025q-W0Cy_6CHHvm8brMaawS-yx8_MhbmdRsBuIX3hHfhnK-NETDwTeFkbwaisO0Pz72XASgzoeGauFue6E1Vt8N_1aolF0yGgCUQCKpFHHNKXE4hiC5jOjffXbs_sn_JGtnWttUdvBOg/Jason%20Bourne%20Official%20Trailer%20%231%20(2016)%20-%20Matt%20Damon%2C%20Alicia%20Vikander%20Movie%20HD%20(2).mp4",
                    ContentType = "video/mp4",
                    Name = "Jason Bourne"
                });
            }
            else if (cardContent.Key == "The Land")
            {
                replyToConversation.Attachments.Add(new Attachment()
                {
                                           ContentUrl = "https://fk5qxa-bn1306.files.1drv.com/y3mUNjU5jaVGRSYFQUv0Vt2Tged9t9HtB8OTT4yhtGFYQVW6l3LZTaqi-2UDLbCNZ9fYXIMBbwrPi7vFQx5mdkSgPkXwyAHQZF5FRu3h2lIA_GFqMVCO-u0OZ6q1hufxrzJyUfkI1FS6d8ziiL3ANoOu-urUdJcDcOyoWTICKlvp-E/The%20Land%20Official%20Trailer%201%20(2016)%20-%20Moises%20Arias%2C%20Machine%20Gun%20Kelly%20Movie%20HD%20(1).mp4",

            }
            else if (cardContent.Key == "Yoga Hosers")
            {
                replyToConversation.Attachments.Add(new Attachment()
                {

                    Name = "Yoga Hosers"
                });
            }
        }
        replyToConversation.AttachmentLayout = AttachmentLayoutTypes.List;
        await context.PostAsync(replyToConversation);
    }

Skype で通話すると、次のようなビデオが表示され、正常に再生されます。
