Hello, we would like to manage purchases for the Windows Store from our servers as described here: https://docs.microsoft.com/en-us/windows/uwp/monetize/view-and-grant-products-from-a-service In order to do this we would require access to the collections Id of the user. Basically we need to call StoreContext.GetCustomerCollectionsIdAsync. We already use this approach in our non-Unity games and would like to continue using it. Is there a way to access this function in the Unity IAP code or from C# code directly? It seems that the Windows namespace is not available by default in our project so we can't call it ourself. Any help is appreciated, thanks.
