A WhatsApp API client that connects through the WhatsApp Web browser app

The library works by launching the WhatsApp Web browser application and managing it using Puppeteer to create an instance of WhatsApp Web, thereby mitigating the risk of being blocked. The WhatsApp API client connects through the WhatsApp Web browser app, accessing its internal functions. This grants you access to nearly all the features available on WhatsApp Web, enabling dynamic handling similar to any other Node.js application.
