使用 Microsoft Bot Framework V4 主动向 Microsoft Teams 中的团队聊天发送消息

Question

我正在尝试从我的 Azure 托管机器人主动向 Microsoft Teams 团队聊天发送临时消息。我已成功向用户与机器人进行的一对一聊天发送消息。

我已经看到 this documentation 详细说明了如何执行此操作，但我相信这是 Bot Framework 版本 3。它使用块块包 Microsoft.Bot.Connector.Teams.Models，版本 4 不再支持它。我无法找到执行此操作的文档。

为了更具描述性：

我有一个机器人，它从我的网络应用程序接收带有警报数据的 POST 请求。当机器人收到其中一个 POST 请求时，它会将消息转发到团队聊天。此消息将在任何上下文之外发送。可以在此处找到我用于转发到 1 对 1 聊天的代码。

/// <summary>
    /// Forwards a message to a personal chat.
    /// The details of who to send the message to is included in the <paramref name="forwardContext"/>.
    /// </summary>
    /// <param name="forwardContext">JSON of the recipient details.</param>
    /// <param name="messageToSend">Text message to send to chat.</param>
    /// <returns>A <see cref="Task"/> representing the asynchronous messsage forward.</returns>
    private async Task ForwardMessageToPersonalChatAsync(JToken forwardContext, string messageToSend)
    {
        // Collect data from JSON input
        var restCmd = forwardContext;
        var toId = (string)restCmd["toId"];
        var toName = (string)restCmd["toName"];
        var fromId = (string)restCmd["fromId"];
        var fromName = (string)restCmd["fromName"];
        var channelId = (string)restCmd["channel"];
        var serviceURL = (string)restCmd["serviceURL"];
        var conversationId = (string)restCmd["conversation"];
        var tenant = (string)restCmd["tenant"];
        var cred_str = $@"toId: {toId}
        toName: {toName}
        fromId: {fromId}
        fromName: {fromName}
        channelId: {channelId}
        serviceURL: {serviceURL}
        conversationId: {conversationId}";
        this.logger.LogInformation(cred_str);
        this.logger.LogInformation($"Forwarding the following message to {toName}: {messageToSend}");

        var uri = new System.Uri(serviceURL);

        Dictionary<string, string> botCreds = this.GetBotCredentials();
        ConnectorClient connector = new ConnectorClient(uri, botCreds["App ID"], botCreds["App Password"]);
        var activity = new Activity
        {
            Type = ActivityTypes.Message,
            From = new ChannelAccount(fromId, fromName),
            Recipient = new ChannelAccount(toId, toName),
            Conversation = new ConversationAccount(false, "personal", conversationId),
            Text = messageToSend,
        };

        try
        {
            MicrosoftAppCredentials.TrustServiceUrl(serviceURL);
            await connector.Conversations.SendToConversationAsync(conversationId, activity);
        }
        catch (System.Exception ex)
        {
            this.logger.LogError(ex.ToString());
        }
    }

如何向团队聊天发送主动消息？
