How to get the Telegram user ID?

The steps are the same for desktop and mobile apps. First, open your Telegram app. Then, type "userinfobot" in your contacts search bar. If you can't find this "profile", try adding an "@" in front of the search query. When you’ve located @userinfobot, click or tap it. Then, select Start at the bottom of the chat.
By clicking Start, you’ve automatically entered "/start." It will prompt the bot to display your user ID, as well as your selected first name, last name, and the language of choice.
Copy the value of the ID field and add it in the configuration of the notification channel.
Click Save or Enable channel in case of the first activation.
