Is there any way of using an external private nuget feed (either an Artifact feed belonging to another organization, or a standalone private (basic auth) enabled nugetserver) as an upstream source in Azure Artifacts?
It is possible in other parts of Azure Devops as a service connection, but I can't find a way of either utilizing service connections nor specify a private external nuget as upstream source in Artifacts. The only options are public nuget servers and feeds present in Devops.
