serviceWorker and fbinstant

[Kanela]

I am trying to create a web push notification for my instant game.

Can I use serviceWorker with fbinstant?

When I try to create the subcription for my worker, I have this message:

* DOMException: Registration failed - permission denied

 

postdata: subcription example:

 subscription = await register.pushManager.subscribe({
        userVisibleOnly: true,
        applicationServerKey: urlBase64ToUint8Array(publicVapidKey)
    });

AFAIK - no, you can't. Not all of the clients can handle with serviceWorkers, so support for it is disabled in IG.
