Is your feature request related to a problem? Please describe.

Hello,

Websocket doesn't seem to be supported.

I tried this from Backend protocol support that gateway api 1.2 introduce but it's not implemented yet it seems.

Is there any other way I can enable websocket support for routes or gateways ?
