StoreKit config file in UITests

I am looking to add a .storekit configuration file to my UITests so that I can verify price, description and purchase flow. I am able to run the custom configuration when running normally in the sim but when launching with XCUIApplication it does not appear to use the .storekit file (products don't load).

Does anyone know how to get the main app to pickup the StoreKit config file while running from a UI Test?
