Question SFU / Media Server Integration

I know this has been asked before but it would be really awesome if someone already successfully used an SFU (we're currently looking at the Janus Server) and would be willing to share some information on how to do it. What the minimal required steps would be to change one of the Render Streaming samples to get this to work.
Any help would be greatly appreciated!

You can expect to connect to Janus by reading the message-formatted documentation, running a demo to see the signaling messages sent and received, and implementing a signaling client that reproduces the sending and receiving of similar signaling messages.
