How can I send files along with text?

I used your technique, and now I can send texts. How do I send attachments of files?
What is the format or structure of the attachment parameter in the WhatsApp Web URL? Is it a separate URL, a file path, or some other format?
Are there any alternative methods or libraries within the Puppeteer ecosystem that can simplify the process of attaching files to WhatsApp message
