Question: How to add an additional App folder which is not a resource?

Description
We've been customizing the dashboard apps for a few weeks now and this repo is incredibly impressive. Really easy to develop custom functionality. The components can be used for any type of dashboard where you retrieve the data using useSwr. What we wanted to do was to add another folder in the apps, that was not a CommerceLayer resource, and build additional functionality into the dashboard to grab data from another source. We would still surround the app with the TokenProvider, so to use the app, a user would still have to be logged into the CommerceLayer dashboard. I am wondering if something like this is possible? Which files need to be changed to add a folder and the required functionality so the folder can be used as a Custom App in the dashboard?
thanks.

PS for the above top of functionality, we used to use React Admin, but your set up is far simpler, plus the integration with all the other aspects of CommerceLayer, makes it very scaleable for a lot of different use cases for any business (every business has customers, orders etc, even if they don't necessarily do this on the front end of a public facing website).
