Anyone managed to detect when browser tabs are closed and respond to the closing of said tab?

Basically, I'm locking to automate toggling of things if a google meet tab is closed in Brave browser. Any suggestions for things that have worked for you?

at first you can check if the tab is already open. other idea: I would try a javascript inside the browser listening to tab closing (maye with beforeunload event) and save this somehow. then ask with hammerspoon via javascript for applications for this stored value.

Here's what I ended up with.. basically watching tab count and the domain existing or not.. hacky, but works.
