Analyze current status of a browser

[superarce]

Hi,

I'm working on a tool to analyze several urls from a shell script. I want to interact with the web page to analyze not only the default status of the page, but also popups or subsections that appear after doing actions.

I've seen the --port argument to connect lighthouse to a running browser.

Is there any way to run lighthouse without passing the url and analyze the current status of the page displayed in the browser?
