有没有办法通过提示选项在网络频道机器人中以按钮的形式显示选项，以便使用C#在V4 SDK中进行多选？

// 创建一个适配器
var adapter = new BotFrameworkAdapter();

// 创建一个处理消息的函数
async Task BotCallback(ITurnContext turnContext, CancellationToken cancellationToken)
{
    // 创建一个按钮卡片
    var card = new HeroCard
    {
        Text = "请选择一个选项：",
        Buttons = new List<CardAction>
        {
            new CardAction { Title = "选项1", Type = ActionTypes.ImBack, Value = "选项1" },
            new CardAction { Title = "选项2", Type = ActionTypes.ImBack, Value = "选项2" },
            new CardAction { Title = "选项3", Type = ActionTypes.ImBack, Value = "选项3" }
        }
    };

    // 创建一个消息活动
    var message = MessageFactory.Attachment(card.ToAttachment());

    // 发送消息活动
    await turnContext.SendActivityAsync(message, cancellationToken);
}

// 添加一个中间件，用于处理消息
adapter.Use(new TeamsMiddleware());

// 添加一个消息处理函数
adapter.OnTurnError = async (turnContext, exception) =>
{
    await turnContext.SendActivityAsync("出现了一个错误，请重试。", cancellationToken: cancellationToken);
};

// 启动适配器
var server = new SocketServer(adapter, 3978);
server.Run(BotCallback);
