How does this bot work, and how to do something similar?

Question

Bots

Good afternoon, there is a @spin2winbot bot in the telegram (not advertising)
When you click on the play button, the bot sends a message with a button, by clicking on which the person is redirected to the site (but if you enter from the application, the site will open inside the application). I want to do something like this so that the site opens inside the Telegram app itself, how can this be implemented?

Answer 1

Any link will open inside the application if the in-app browser is enabled in the application. It does not depend on you and the bot, only on the user settings.
