Setup push notifications with next-pwa

[vamsimudadla]

Is next-pwa enough for setting up push notifications or do we need any third party services like onesignal to send and manage notifications. If next-pwa is enough to setup, please tell me how to do it to make it work both in online and offline mode.

@vamsimudadla It seems this repo is dead and the maintainer cannot be contacted for so long now. I've made an immediate response by resurrecting this repo ImBIOS/next-pwa.
