I see that `cloudflared access` has support for a proxy #317. I'm trying to use `cloudflared tunnel` as well behind a corporate firewall, but this doesn't seem to support proxy?...

It would be handy to have HTTP and WebSockets running on the same port instead of the WebSocket being a random other port. Useful for when there is a firewall/nat-forwarding.
