Publish library to Orchestrator from the commandline

I would like to publish a library to Orchestrator using the command line (NOT Studio). This is for a CI Build. I’ve used the UiPath task available in DevOps but using that to deploy pushes the library as a package to Orchestrator, which is not what I want. I’m able to pack the library using the UiPath task but I don’t know the setting to publish to the Orchestrator feed using Nuget.

Is there an ApiKey?
What feed url should I use?
Does it use basic authentication?

I created a service connection in DevOps with https://[orchestratorHost]/nuget/activities as the feed url and basic authentication but that didn’t work.

Found the ApiKey in the settings but still unable to nuget push packages using that. Is this even possible or am I wasting my time?
