Is it possible to use a button embedded within a thumbnail card to trigger another search?

1. I am using Search Extensions to provide the user with a search experience through the command bar and compose areas of teams.
2. I am currently in the exploration phase and am using the C# Microsoft.Bot.Schema library to create my thumbnail cards. Below is the C# that i am currently using to return search results.

var previewcard = new ThumbnailCard
{
    Title = result.Title.Raw,
    Text = result.Description.Raw,
    Subtitle = result.Source.Raw,
    Images = new List<CardImage> { new CardImage { Url = "https://<url>.ngrok.io/extensionDOCX_x256.png" } },
    Buttons = new List<CardAction>
    {
        new CardAction(
                "openUrl",
                "WebDav Link",
                value: "<webdav url for document>")
        }
    }
};

 3. I don't really have any repro steps as I was doing research and found documentation on the ListCard but noticed that it was unsupported for teams bots. 

I am vaguely aware that teams has some functionality for having bots trigger popup windows but i cannot find the documentation for that feature again.
