Describe the missing service. Please provide useful links.
Centrifugo is an open-source real-time messaging server. Centrifugo can instantly deliver messages to application online users connected over supported transports – WebSocket, HTTP-streaming, SSE/EventSource, WebTransport, GRPC. Centrifugo is built around channel concept – clients subscribe to channels to receive publications, different subscriptions are multiplexed over a single connection to the server. So Centrifugo is a user-facing PUB/SUB server, with many additional features around this core concept.

Describe the solution you'd like
Sending the message to Centrifugo over websockets in order to handle notification in client facing webapp

I have raised a PR, the webpush tests are failing. These are not altered in this PR. Can someone help here. This test also fails locally.
