How to know which Adaptive Card button is pressed when using Microsoft Teams and Action.Submit

Question

I've created a bot using Microsoft Bot Framework Composer and displaying the following Adaptive Card. How can I determine what button is pressed when the message is submitted using Action.Submit and Task/Fetch?

{
  "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"
}

My bot correctly receives the submitted message, but I cannot tell which button is pressed. The following is an example of this.activity sent. I can see the msteams type is set to task/fetch, but cannot tell what button was pressed in the above card.

{
  "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"
}

It looks like I need to pass a value or data field in the msteams node but not sure how.

You can include additional hidden properties in the data object, if required.

{
  "type": "Action.Submit",
  "title": "submit",
  "data": {
    "msteams": {
        "type": "task/fetch"
    },
    "Value1": "some value"
  }
}
