How to customize Adaptive-Cards in WebChat?

Question

This question is an extension of my previous question. (How can I put "AdaptiveActionSet" in "AdaptiveColumn"?)

At the time, I didn't know much about the customization of adaptive cards and the WebChat.html file.

The image above is the layout of the adaptive card I want. The Reserve button on the right is Action.OpenUrl button.

To place a button like that, I need to put an ActionSet in a Column. However, typical Adaptive Cards do not show ActionSet in Column as in the image above. The content type is shown below. ContentType = "application/vnd.microsoft.card.adaptive" (In web chat)

To solve this, I have to customize Adaptive Cards, but I'm not sure how.

(Ashamed, I referred to the link below but still I can't customize the card.

Bot Connector service is not using latest Adaptive Cards #87

Can you show me a way to solve this or show a simple customized card example? Please.

Below is the code I wrote.

My Adaptive Cards Code :

card.Body.Add(new AdaptiveColumnSet()
{
    Columns = new List<AdaptiveColumn>()
    {
        new AdaptiveColumn()
        {
            //(~Date, No problem)
        },
        new AdaptiveColumn()
        {
            //(~Price, No problem)
        },
        new AdaptiveColumn()
        {
            Items =
            {
                new AdaptiveActionSet()
                {
                    Actions =
                    {
                        new AdaptiveOpenUrlAction()
                        {
                            Url = new Uri("https://www.SomeUrl.com"),
                            Title = "Reserve",
                            Style = "positive",
                        }
                    }
                }
            },
            Width = "auto",
        }
    },
});

var reply = turnContext.Activity.CreateReply();
reply.Attachments = new List<Attachment>
{
    new Attachment()
    {
        ContentType = "application/vnd.microsoft.card.custom",
        Content = card
    }
};

My webChat.html :

const attachmentMiddleware = () => next => card => {
  if (card.attachment.contentype === 'application/vnd.microsoft.card.custom'){
    card.attachment.contentType = 'application/vnd.microsoft.card.adaptive'
  }
  return next(card)
};

window.WebChat.renderWebChat({
    directLine: botConnection,
    styleOptions,
    adaptiveCardHostConfig,
    attachmentMiddleware
}, document.getElementById('webchat'));

document.querySelector('#webchat > *').focus();

As above, ContentType = "application/vnd.microsoft.card.custom"

If I assign custom to contentType,

I get an error called No renderer.

Using AdaptiveColumn's SelectAction solved the problem. And it by using AdaptiveTextBlock and SelectAction together and specifying Width.

ex)

Items =
    {
        new AdaptiveTextBlock()
        {
            HorizontalAlignment = AdaptiveHorizontalAlignment.Center,
            Color = AdaptiveTextColor.Light,
            Text = "Reserve",
            Weight = AdaptiveTextWeight.Bolder,
         }
    },
    SelectAction = new AdaptiveOpenUrlAction()
    {
        Url = new Uri($"{someurl}"),
        Title = "rsv",
        Id = "bb" + cnt,
    },
    Width = "50px"
