That's fine here too.

You'll need to use the information you get from the first API call to pass
along to noVNC, which then uses that to open a websocket connection.

No, we have no explicit (developer) documentation for that, but besides our
open source code there are a few forum threads about this, e.g. a recent one:

https://forum.proxmox.com/threads/no-ticket-error-even-with-the-ticket-in-api2-json-nodes-pve-qemu-100-vncwebsocket.123530/

Wile chunked into multiple posts it contains a lot of relevant info for how
this works and what one needs to do.
