How to add DLC to the store listing with expansion files

We are working to provide DLC for our customers. We want to enable the users to unlock an asset from within our app. In our case, skins for our DJ decks.

Technically, the skin is included in the app and the user can unlock it by purchasing it from the Oculus store. However, we are not currently releasing any expansion files. Instead, we have uploaded a TSV to our In-App Purchases page on our Dashboard.

How can we make this available to the user via a Store listing much like the Rock Band VR page.
