Per-message Compression not working with uWebsocket backend

Hi, I'm using Websocket-sharp in my Unity game as client that is connecting to a uWebsocket backend server.
We want to enable Per-message Compression for this connection but the problem is that when I enable compression in client with following line before connect:

ws.Compression = CompressionMethod.Deflate;

the server refuses the request from the client for connection.
We also reproduced this issue with ws library in node js as backend with its provided example configuration, but the problem persists. When we set serverMaxWindowBits in ws library to default negotiated value, the client can connect to the server properly.

Now my question is, Is there any way that we can control this serverMaxWindowBits from WebSocket-Sharp client?

Thanks

Start with the CompressionMethod.Deflate setting shown in the issue and trace how the client negotiates per-message compression parameters during the WebSocket handshake. Compare that negotiation with the uWebsocket and Node.js ws behavior described; done means establishing whether serverMaxWindowBits can be controlled and identifying the required client-side change or limitation.
