Configuring dashboard + authorize filter and Owin in different Web APIs

I have my Owin implementation in a Web API and Hangfire server in another. In this scenario, how should I implement the filter authorization?

The issue provides no file, test, or entry point. Start by locating Hangfire's dashboard authorization configuration and the Owin setup across the two Web APIs; done means documenting how authorization works when the dashboard and Owin implementation are separate.
