How can this be done?

I’ll make a reservation right away: I don’t remember if this works if the dialogue with the bot has already begun.

Bots have an external linking mechanism that allows you to pass additional parameters at startup. For example, to transfer the user's authorization token in order to connect his account with some external service.
Each robot has a link with which you can start a dialogue with it - https://t.me/<имя бота>. You can add parameters to this link, *startor startgroupwith a value of up to 64 characters. Example:
https://t.me/triviabot?startgroup=test
The characters allowed are AZ, az, 0-9, _ and -. We recommend using base64url to encode parameters.
Following the link with the start parameter will start a chat with the bot, while the START button will be displayed in the text input field. When clicking on a link with the startgroup parameter, the user will be prompted to add the bot to one of the available groups. As soon as the user confirms his action (presses the START button or selects a group), the bot will receive a message in the following format:
/start PAYLOAD
PAYLOAD will contain the value of the start or startgroup parameter that was passed in the link.
