Web WhatsApp ChatBot -- 2

We are using a free API to build a bot for WhatsApp. Nowadays we could achieve to send and receive messages through web WhatsApp, but we need to expand the functionality to send every type of files, like photos, pdfs, etc. What we need is a JavaScript Senior Developer, to build the missing script for this purpose. The entire project run in a Linux distribution, using some drivers, and python to inject JS into a browser and interact with it like a humanBot.
