How can I send a document with the original document name?

General

I have the node-red-contrib-telegrambot 15.1.10. How can I sent a document with the original name of the document? (not "data.pdf" please). I have been trying to write "filename: whathever" in every object but I can't find the solution.

This is an example of what I have been made:
