I have a issue for chrome 67+ the permission window is never displayed, according to the documentation (push-notification) the parameter applicationServerKey is mandatory form chrome, Is it possible to add this parameter? I think that this parameter should be added inside the backend to support it.
The Line in the SDK Library:
From Chrome 68 (beta) the applicationServerKey is mandatory for subscribing push notifications. On the next release of IBM Cloud Web-push SDK we will add applicationServerKey option. Kindly follow this - issue: 403534206
