[FEAT]: chatbot generate downloadable file output

[Mirgiacomo]

What would you like to see?

Many times in various workflows it is seen necessary to be able to download a file containing the output of a chatbot response.

Let me explain further:

If I ask "Generate me an excel with 10 random users with first name, last name, email and password and save it to an .xlsx file," it would be very convenient for the chatbot to create a file (maybe temporary) and if the user presses on it he can download it.
