Sending HTTP headers during initial MQTT connection over websockets

[Hardwood2112]

Hello!

I have a MQTT broker that is behind Cloudflare Access, for services to access that MQTT broker over Websocket I need to send 2 additional headers during the initial connection. The ESP-IDF MQTT Client implementation doesn't seem to allow for any extra headers to be passed during the initial HTTPS connection. Does anyone know of a way this could be implemented?
