Atlaskit Smart Card, how to configure or set up client

I’ve got a connect app set up with AtlasKit. I’m looking for the simplest way to render Jira Issues in the canonical format, which looks to be using Smart Cards.
However, it looks like the built in client is only for private use. Is there a way to use Smart Card with the built in client so that I can do something like this?

        client={new Client()}

Or do I need to write my own API to provide the JSON-LD and then write my own client to connect to it?
