Accessing Community Shared Libraries in Relume: How It Works

Is it possible to access community shared libraries from within Relume? (site or extension?) Or is a direct link shared by the owner themselves the only way to use a community shared library? We are working on creating a library of components for CartGenie. I assumed that it would be discoverable by anybody inside of Relume but it doesn't appear that is the case? Please let me know if I've missed anything!
