Which page to test this? I can only found /control/ but it doesn't have WebSocket feature, whereas, by looking into settings.py, the redis_connection_kwargs is used for channel layer config, which belongs to WebSocket feature.

Perform actions on the /control/ page that would trigger WebSocket communication (e.g., starting or stopping a stream, sending a message, etc.).
Then check the 'WebSocket' tab in the developer tools to see if messages are being sent and received.
