Rocket Terminal Emulator

My company uses Bluezone Mainframe Display and I have created an intranet web app with JavaScript coding to scrape information from Bluezone. This currently only works in Internet Explorer as it uses ActiveX for communication. With IE going away eventually I started looking for solutions that would allow communication using Chrome and came across the Bluezone Extension in the Chrome Web Store that says it allows communication between web script and sessions but requires URL pattern match to be added. i cannot find any information on URL pattern matching.

Does anyone have any experience using the Bluezone Chrome Extension and can maybe point me in the right direction?
