There was a problem hiding this comment.
it is possible that the message received is not necessarily the ack of the message you send. For example, when someone else just published a message to the group.

Well the _send_receive method is private (starts with underscore) so you are not supposed to use it. It is only used once during the setup in the connect method were it needs to check joingroup returned an ack response. After that the client of the WebPubSubGroup can only do fire and forget, and add a add_listener to receive out of band messages from others. If the user wants to do message correlation they will have to do it in their own payloads.
…y. Azure web pub sub sockets do eventually timeout afer a couple days.

This sample helps stitch together some different things to make a nice fully bidirectional communication channel using Web Pub Sub groups.
I used this code to implement a realtime messaging system to connect various distributed components of this system: https://github.com/microsoft/ada/tree/main/AdaKiosk and it has been up and running for a couple weeks now, it works great!
