How to link to Telegram bot from html5 game?

Question

Bots

Good afternoon!

How to make a link from HTML-5 game back to telegram? The bottom line is that users of html games are growing, but they don’t even know about the bot. After losing the game, I organized a link like t.me, but the "send message" button does not work there. I've already tried everything and tg: and so on. It is necessary that the built-in browser closes and the chat with the bot opens.

Thank you!
