HPA with websocket server

We have a websocket server running in AKS cluster that maintains websocket connections with service running on Edge. The timeout ( > 2 hours ) for this connection is configurable and the client reconnects after this configured time.
Though the number of connections remain constant the messages transferred varies. Since the connections are persistent and long term in case the HPA triggers we need a way to redistribute the connections when new pods are added. What would be the best approach to handle this ??

You can format your yaml by highlighting it and pressing Ctrl-Shift-C, it will make your output easier to read.
