This enables real-time communication between distributed instances of your app.
Config

A unique channel name used to synchronize messages between servers.
This can be any string, but must be the same across all instances sharing events.
Output
- Returns
ASSEPublisherinstance that can be used to register connections and publish events.

Create and start the SSEPublisher once during server startup using a server hook.
Access it later with Get Registry Value.
Avoid initializing resources like this inside API handlers.
