List Template for FB using Bot framework node.js V4

问题

Can anyone please help me to include list view in Facebook Channel using Bot framework? I saw examples as shown here List template. I don't know whether this is the exact way in which we need to give the attachments. Also I didn't know the equivalent for sourceEvent method in Bot framework v4. Another useful link is as follows FB Messenger Message Template. See the image given below. I need to put the link for the image and once we click the link it should open another page also the image should be clickable image as in the example for C# Clickable HeroCard images using tap property. Both functionality should work. I tried using HeroCard (but the url that needs to open-up had CORS origin issue. I tried using Adaptive card but it is not supported in Facebook as of now. So, I thought to use List Template for Facebook. Is there anyway to achieve this?

You can send Facebook List Templates through the Microsoft BotFramework by adding the Facebook attachment to the activity's channel data. The list template type doesn't seem to be supported, but you can set the type to generic and add multiple elements to the attachment to get the same result. See the example below.

await turnContext.sendActivity({
    channelData: {
        "attachment": {
            "type": "template",
            "payload": {
              "template_type": "generic",
              "elements": [
                {
                    "title": "Three Strategies for Finding Snow",
                    "subtitle": "How do you plan a ski trip to ensure the best conditions? You can think about a resort’s track record, or which have the best snow-making machines. Or you can gamble.",
