How to write a WhatsApp bot on Node.js.

- Responding and responding to a command
- Output the ID of the current chat (in the BOS or in the conversation)
- Output the name of the person who communicates with the bot
-Sending files of various formats (pdf, jpg, doc, mp3, etc.)
- Sending voice messages (*. ogg files)
