How to address by name
We take variable this_user from Variables in Botmother section, and add the value of the name firstname to it, we get variable this_user.firstname.
We write the text of the message:
Hello, {{this_user.firstname}}
The bot will output such a message to the user:
Hello, John
If you need to output the user's first and last name, use this_user.full_name variable. And if you output only the last name use this_user.lastname.
This is how you can display a clickable username:
@{{this_user.username}}
This can be useful in the text of the Alert component, so that you can immediately go to the chat with the user by clicking on the link.
This method will work if the user has a username in Telegram.
