How to communicate with youtube rtmp server in unity

I am looking for a way to transmit to YouTube rtmp server, which is one of the OBS studio functions with Unity.

When I thought about it, I thought that I could do rtmp communication without a separate web server using the youtube live streaming api.

But when I tested the various methods, they failed.

Is my current approach correct? Or do I need to communicate with the youtube rtmp server through a separate web server?

Please let me know if there is another solution

thank you

I imported google-api-dotnet-client into Unity using nuget.
