How to use @mention in facts in a Teams MessageCard ?

Dylan 20 Reputation points


As the example below, given by Microsoft at, I would like to reuse this exact same MessageCard with the "table" part ("facts" in code) and implement a user mention instead of "Unassigned".

I can create two cards, one with a simple mention Like "Hi @User", and another with a table, but I can't fuse them together, the code structures aren't really the same.

    You can add @mentions within an Adaptive Card body for bots and message extension responses. like below-
    If you want to use FactSet please refer the below sample-

      "contentType": "application/",
      "content": {
        "type": "AdaptiveCard",
        "body": [
            "type": "TextBlock",
            "text": "Hi <at>John Doe</at>"
        "$schema": "",
        "version": "1.0",
        "msteams": {
          "entities": [
              "type": "mention",
              "text": "<at>John Doe</at>",
              "mentioned": {
                "id": "29:123124124124",
