我正在嘗試按照Microsoft Docs 中的這篇文章將我們的版本 3 代碼遷移到版本 4。但是，我不確定如何重寫 Luis 對話框。必須做什么？我在 onturnasync 中添加了以下代碼，現在不確定如何重寫 AfterFAQ resume 方法。請幫助我重寫這些現有的 Luis 方法：      //The LUIS dialog service call the back the method if the conversation is part of Greeting intent    [LuisIntent("Greetings")]    public async Task Greetings(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result)    {        needMoreInformation = false;        qnaInvalidMessageCount = 0;        var messageToForward = await activity;        string[] supportList = { "HELP", "FEEDBACK", "SUPPORT", "ESCALATE", "AGENT" };        string qnaAnswer;        if (messageToForward.Text == null || supportList.Any(x => x == messageToForward.Text.ToUpper()))        {            await context.PostAsync("Please reach out to ...");            context.Wait(MessageReceived);        }        else if (GreetingColl.TryGetValue(messageToForward.Text.Trim().ToLower(), out qnaAnswer))        {            await context.PostAsync(qnaAnswer);            context.Wait(MessageReceived);        }        else        {            await context.Forward(new QnAGreetingsDialog(), AfterFAQDialog, messageToForward, CancellationToken.None);        }    }修改代碼： public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))    {        if (turnContext.Activity.Type == ActivityTypes.Message)        {          ...           var luisResults = await botServices.LuisServices[LuisKey].RecognizeAsync(turnContext, cancellationToken);                    var topScoringIntent = luisResults?.GetTopScoringIntent();                    var topIntent = topScoringIntent.Value.intent;
