Use this if opening the app inside Telegram keeps failing. You'll need to have already opened a chat with our bot at least once (send it /start if you haven't).
Find it via any "what's my Telegram ID" bot, or check your Profile page if you're already logged in somewhere.
If that ID is valid and you've started a chat with our bot, a code was just sent there. Check Telegram.
