How can I install WebRTCSink on Ubuntu 22.04

[GST Developer]

Is this a camelCase vs snake_case issue with “peer_id” vs “peerID” ?

The js api stuff is working fine,browser to browser, interacting with the signalling server, but the webrtcsink doesnt seem to like the message coming back from the signalling server.
