Ask HN: Where to learn good design practices for Telegram Bots?

I want to use a telegram bot as the user interface for a logging/reporting system I operate. Interactions are pretty structured, so there is no need for fancy NLP machine learning stuff. I would like to write this 'right' the first time, or at least lay a decent foundation. But I've only built some simple bots as experiments. I am struggling to find any decent tutorial or example codebase that demonstrates good practices for a robust, small-scale (<100 users) bot system. There just seem to be endless 'Hello, World'-level summaries online that are zero help. Any guidance on writing a decent quality telegram conversation bot?
