Which constructor to use to create a chat bot?

Question

Bots

Greetings
It is necessary to make a simple Telegram chat bot where the user selects the type of action and enters a value. For example
Create Barcode -> Enter value -> the request is sent to our backend script, which returns the answer -> sending the answer to the messenger
I heard a lot about chat bot designers, please advise which applications to look for this?
Thank you!
