How can I use Puppeteer to interact with a browser extension effectively?

Puppeteer interact with extension is a pain, but I found a decent solution. Use `chrome.debugger` API to trigger extension actions.

Also, this tool called Puppeteer-Extension-Testing on GitHub is a lifesaver: [GitHub Repo](https://github.com/example). It has examples for automating popups and buttons.

Good luck, and let us know how it goes!
