Actually i spoof the location to say you're at area 51 in my remote isolated browser. It's done using chrome DevTools protocol, which is very simple to use, using the method `Emulation.setGeolocationOverride`[1]

You can try the demo https://demo.browsergap.dosyago.com/

and you want to go to the "Browser Geolocation" link at this site https://mylocation.org/
