使用 Microsoft Teams 和 Action.Submit 时如何知道按下了哪个 Adaptive Card 按钮

我使用 Microsoft Bot Framework Composer 创建了一个机器人并显示以下自适应卡。使用 Action.Submit 和 Task/Fetch 提交消息时，如何确定按下了哪个按钮？

{
  "type": "AdaptiveCard",
  "body": [
    {
      "type": "TextBlock",
      "size": "Medium",
      "weight": "Bolder",
      "text": "Publish Adaptive Card Schema"
    }
  ],
  "actions": [
    {
      "type": "Action.ShowCard",
      "title": "Set due date",
      "card": {
        "type": "AdaptiveCard",
        "body": [
          {
            "type": "Input.Date",
            "id": "dueDate"
          },
          {
            "type": "Input.Text",
            "id": "comment",
            "placeholder": "Add a comment",
            "isMultiline": true
          }
        ],
        "actions": [
          {
            "type": "Action.Submit",
            "title": "OK",
            "data": {
              "msteams": {
                "type": "task/fetch",
                "value": {
                  "option": "opt1"
                }
              }
            }
          }
        ],
        "$schema": "http://adaptivecards.io/schemas/adaptive-card.json"
      }
    },
    {
      "type": "Action.OpenUrl",
      "title": "View",
      "url": "https://adaptivecards.io"
    }
  ],
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "version": "1.3"
}

我的机器人正确接收了提交的消息，但我不知道按下了哪个按钮。以下是发送的 this.activity 的示例。我可以看到 msteams 类型设置为任务/获取，但无法判断上面卡片中按下了哪个按钮。

{
  "type": "invoke",
  "id": "",
  "timestamp": "2021-06-29T16:57:27.551-05:00",
  "localTimestamp": "2021-06-29T16:57:27.551-05:00",
  "localTimezone": "America/Chicago",
  "serviceUrl": "https://smba.trafficmanager.net/amer/",
  "channelId": "msteams",
  "from": {
    "id": "",
    "name": "Mike",
    "aadObjectId": ""
  },
  "conversation": {
    "conversationType": "personal",
    "id": "",
    "tenantId": ""
  },
  "recipient": {
    "id": "",
    "name": "csharpdemo"
  },
  "locale": "en-US",
  "entities": [
    {
      "type": "clientInfo",
      "locale": "en-US",
      "country": "US",
      "platform": "Windows",
      "timezone": "America/Chicago"
    }
  ],
  "channelData": {
    "tenant": {
      "id": ""
    },
    "source": {
      "name": "compose"
    },
    "legacy": {
      "replyToId": ""
    }
  },
  "replyToId": "",
  "value": {
    "data": {
      "type": "task/fetch"
    },
    "context": {
      "theme": "default"
    }
  },
  "name": "task/fetch",
  "callerId": "urn:botframework:azure"
}

看起来我需要在 msteams 节点中传递一个值或数据字段，但不确定如何传递。
