How does webinar custom live streaming works on recieving end?

Hi all,

I want to live stream from Zoom webinar to my website, so anyone without joining the meet can access live stream of webinar. Zoom allows to stream on YouTube & Facebook but there is a custom option as well which ask to enter stream URL and key. (doc)

I don’t know what to search for it exactly and I’m not getting any results. I did studied RTMP server a bit but not sure if that applies to my case.

On my website I’m running PHP in backend with NodeJS for socket.io server. But I’m comfortable with any implementable solution as long as I can live stream Zoom webinar straight on my webpage.

If you know about this, or some reference materials, that would help me a lot! Thanks in advance!
