Link unfurling using bot in Teams helps you to register your app. And helps to receive an invoke activity, when the URL with domain is pasted into the compose message area. The invoke activity contains the full URL and you can respond with a card. Users can unfurl the link using bot with additional information to get an enhanced experience.
