Esp32 WebSocket Sample

I've noticed the azure-iot-sdk-for-csharp automatically switches over from mqtt port 8883 to mqtt over websocket on port 443 when the port is blocked.

I went looking for a websocket example for the esp32 but could not find one. Does anyone here know of a Azure IoT Hub websocket example for the esp32?

Is implementing websocket, as simple as modifying transport_tls_esp32.c to use websocket and sending the wss upgrade http get? Can the websockets implementation be isolated to changes made only in transport_tls_esp32.c ?
