Microsoft Bot Framework：SigninCard未显示在电报中

Question

我尝试使用Microsoft Bot Framework创建Telegram bot客户端，当我使用此框架创建signincard时，signincard成功创建并且我可以看到Microsoft Bot Emulator中的按钮但是当我发布到服务器并使用Telegram测试时，signincard没有显示在请告诉我如何解决它。

代码：

            Activity reply = null;
            ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl), "", "");

            if (activity.Type == ActivityTypes.Message)
            {                    
                if (activity.Text == "/start")
                {
                    reply = activity.CreateReply($"Welcome, please select an option");
                    reply.Recipient = activity.From;
                    reply.Type = ActivityTypes.Message;
                    reply.Attachments = new List<Attachment>();

                    List<CardAction> cardButtons = new List<CardAction>();
                    var helpAction = new CardAction()
                    {
                        Image = "",
                        Title = "Get Menu",
                        Type = "imBack",
                        Value = "help"
                    };

                    var contactAction = new CardAction()
                    {
                        Image = "",
                        Title = "Contact Us",
                        Type = "imBack",
                        Value = "contact"
                    };
                    cardButtons.Add(helpAction);
                    cardButtons.Add(contactAction);

                    var sc = new SigninCard()
                    {
                        Buttons = cardButtons,
                        Text = ""
                    };

                    Attachment attach = sc.ToAttachment();
                    reply.Attachments.Add(attach);
                }
                else
                {

                }
            }
            await connector.Conversations.ReplyToActivityAsync(reply);

抱歉英语不好。

我认为登录卡类型必须为＆＃34; 登录＆＃34;，而值应为 url 字符串

工作代码：

replyActivity.Attachments = new List<Attachment>();

var cardButtons = new List<CardAction>();
var plButton = new CardAction
{
    Value = auth.SessionUrl,
    Type = "signin",
    Title = "Connect"
};
cardButtons.Add(plButton);
var plCard = new SigninCard("You need to authorize to use Quick Book feature", cardButtons);

var plAttachment = plCard.ToAttachment();
replyActivity.Attachments.Add(plAttachment);
replyActivity.Text = "Should go to conversation, sign-in card";
