How to use QR codes to open a specific chatbot flow without typing a keyword?

Hi!

I’m building a Telegram chatbot to collect reviews for multiple admins. The goal is to track which admin brings more clients who leave feedback.

I need each admin to have a unique QR code that opens the bot and immediately starts the correct flow (for example, without the user having to manually type something like test_review).

Right now:

If I scan the QR code with an admin tag and open the bot, it only sends /start without triggering the flow.
If I manually type the keyword (e.g. test_review), the correct message is sent

Is there a way to make the QR code open the bot and trigger the flow automatically?
