REQUIREMENT: https://ideas.cdq.ch/ideas/IPOC-I-487
Create Google Chrome extension (there is no such on Chrome Web Store) (because of Chromium engine, it would work on Chrome, Edge, Brave, and many more) that would show red/green icon if the domain (company) is on sanction list or not. Or maybe show some warning website, like it is done when one is trying to open page with unsecure HTTPS certificate.
