The HITL mini app runs inside Telegram, so reviewers can answer without installing anything else. A review step sends to Telegram when Telegram is on under Send to in its Reviewers settings.

​
Get started

Open @Human_ApprovalBot in Telegram and launch the mini app. It signs you in with your Telegram account; if you already use HITL, sign in with your email once to link the two.

The Dashboard lists what is waiting for you. Open a request, choose your answer under Your response, and tap Submit Response.
