Can you run a background iBeacon/Eddystone scan in web-bluetooth using a service worker?

With the release of new web-bluetooth features, I believe iBeacon/Eddystone beacon scanning is possible in PWAs using web-bluetooth. I am running a use-case and I would like some help on achieving a background service worker, which scans for beacons in background using chrome service-workers or something similar in smartphones?

Is this possible and if yes how?
