Notifications via request
Notifications are usually configured through Alert component. But you can also configure notification using Request component.
On Telegram
The request method is GET.
Request URL — https://api.telegram.org/bot1/sendMessage?chat_id=2&text=3
where:
1 is the bot token on Telegram;
2 is platform_id of the user who will receive the message (we take it in the Users). It works only for Telegram users;
3 is the notification text, use + sign instead of spaces.
