Currently impossible to add StoreKit to UE5.8?

Since 5.8 is the cutting edge dev branch, is there a “more correct” place to ask about this or is this the best place to ask about this?

EDIT: according to the documentation on the GitHub page this is the wrong category. I have created a new post here Impossible to add Apple StoreKit to a UE 5.8 project

Please post replies there. Thank you
