All we did was post adaptive card that looks like this:

{
  "type": "AdaptiveCard",
  "body": [
    {
      "type": "Image",
      "id": "headerImage",
      "url": "${headerImageUrl}",
      "horizontalAlignment": "Left",
      "size": "Stretch"
    },
    {
      "type": "ColumnSet",
      "columns": [
        {
          "type": "Column",
          "width": "stretch",
          "items": [
            {
              "type": "TextBlock",
              "size": "Large",
              "weight": "Bolder",
              "text": "${title}",
              "id": "cardTitle",
              "wrap": true
            }
          ],
          "horizontalAlignment": "Left"
        },
        {
          "type": "Column",
          "width": "83px",
          "items": [
            {
              "type": "Image",
              "url": "",
              "size": "Stretch"
            }
          ],
          "id": "completedMark",
          "horizontalAlignment": "Right",
          "$when": "${isCompleted}"
        }
      ],
      "horizontalAlignment": "Left"
    },
    {
      "type": "Image",
      "id": "mainImage",
      "altText": "Loading",
      "url": "${imageUrl}",
      "size": "Stretch"
    },
    {
      "type": "Container",
      "items": [
        {
          "type": "TextBlock",
          "text": "${bodyTitle}",
          "wrap": true,
          "id": "bodyTitle",
          "spacing": "Small",
          "fontType": "Default",
          "weight": "Bolder"
        },
        {
          "type": "TextBlock",
          "text": "${bodyText}",
          "wrap": true,
          "id": "bodyText"
        }
      ],
      "id": "textContainer"
    }
  ],
  "actions": [
    {
      "type": "Action.Submit",
      "title": "${buttonTitle}",
      "data": {
        "msteams": {
          "type": "task/fetch"
        },
        "data": {
          "type": "nudge",
          "link": "${link}",
          "nudgeId": "${id}"
        }
      },
      "$when": "${isButtonEnabled}"
    }
  ],
  "$schema": "http://adaptivecards.io/schemas/adaptive-card.json",
  "version": "1.5"
}

Then pressing button from "actions" section. It is handled by Microsoft.Bot.Builder.Teams.TeamsActivityHandler.OnTeamsTaskModuleFetchAsync:

protected override Task<TaskModuleResponse> OnTeamsTaskModuleFetchAsync(ITurnContext<IInvokeActivity> _, TaskModuleRequest taskModuleRequest, CancellationToken ct) 
{ 
using var document = JsonDocument.Parse(taskModuleRequest.Data.ToString() ?? string.Empty); 
var dataElement = document.RootElement.GetProperty("data");
// Extracting action params and populating taskInfo 
... 
var taskInfo = new TaskModuleTaskInfo 
{ 
Url = uri, 
FallbackUrl = uri, 
Title = popUp.Title, 
Width = popUp.Width.ToString().ToLower(), 
Height = popUp.Height.ToString().ToLower() 
}; 

return Task.FromResult(new TaskModuleResponse { Task = new TaskModuleContinueResponse { Value = taskInfo } }); 
}

However, popup appears before it enters OnTeamsTaskModuleFetchAsync.

We encountered and were able to document this issue 2025-03-20 in PC and browser Teams clients, unfortunately I cannot figure out what was the client version. I failed reproduce it as of 2025-06-30 in our bot, but spotted this behavior in another bot, which is not managed by us, so we decided to investigate.
