How the TWebPushNotifications Demo Works

Has anyone managed to get the WebCore Demo Basics \ PushNotifications to work? I looked at the demo, it has a VCL server, but without a source. I looked at the documentation, but it doesn't say anything about the demo. I searched here on the TMS forum and found nothing about TWebPushNotifications. Any tips for this to run? Stone path?

The demo is designed to work with the push server that we installed on our own server.

At this moment we have not yet made the push server code itself adaptable. This is something considered for future developments.
