How to connect WebsocketDemultiplexer with pgpubsub

[fwroman]

Hello, I was wondering if is there a way to connect from WebsocketDemultiplexer custome class to postgresql using pgpubsub?. I'm trying to broadcast postgres notifications through WebsocketDemultiplexer, or could you give one solution to achieve this please? I've noted WebsocketDemultiplexer has an own channel and it can't be used with websocket.receive in routing.py

I'm newbie using channels. Thanks in advanced.
