loveproyt2/telegram-otp-bot ? reverse-engineered prompt

Build me a simple Telegram bot in Python for IVASMS that helps with OTP handling.

I want users to be able to start the bot in Telegram, connect whatever OTP flow is needed, and get clear messages back when an OTP is sent, received, or fails. Make it feel polished and easy to use, with basic commands, clean replies, and sensible error handling.

If there are any setup details or current best practices I should follow for Telegram bots or the IVASMS side, look them up online if you need to. Keep the code easy to run, with a straightforward config setup and anything needed for deployment already wired in.

Also include a small README update that explains how to install it, set the required tokens or keys, and run it locally.
