For my setup, I used UDP port 443. For the vast majority of situations it works well as TCP 443 is for secure internet traffic. It seems admins often blanket 443 port open regardless of protocol 🙃

If you’re still looking for a solution, have you thought about using a native JavaScript solution?

It could be as simple as placing a click listener on the body element of each page and then having a list of CSS selector rules. Matches is a JS function that you can pass a CSS selector too, so each click that occurs you can loop through an array of selectors.

Alternatively, that array of selectors could be the elements you attach the listeners to directly.

I’d be happy to help create some examples, if you have any extra context 👍
