如何在提交操作中编辑MS Bot框架适配卡

using Microsoft.Bot.Builder;
using Microsoft.Bot.Schema;

// 创建适配卡对象
var heroCard = new HeroCard
{
    Title = "Sample Card",
    Subtitle = "This is a sample card",
    Text = "This is some sample text",
    Images = new List<CardImage> { new CardImage("https://example.com/image.jpg") },
    Buttons = new List<CardAction> { new CardAction(ActionTypes.OpenUrl, "Learn More", value: "https://example.com") }
};

// 创建消息活动
var message = MessageFactory.Attachment(heroCard.ToAttachment());

// 发送消息活动
await stepContext.Context.SendActivityAsync(message, cancellationToken);
