How to implement reflinks in telegram bot?

Question

Python

I saw it implemented in many bots, for example
t.me/store_bot?start=whattomine_bot the link immediately takes you to some command.
I want to implement something similar, to track users who went to the bot via a link from another user of the form: t.me/my_bot?start= chat.id of the inviting user.
Well, therefore, count how many specific chat.id invited users to the bot
