I'm working on integrating Google Analytics 4 into our NOP 3.9 site, and was wondering if there is a way to grab the SKU for the item being added to the cart via the popup, so that it can be passed via a gtag event?

Is there a variable within the SevenSpikes.Nop.Plugins.AjaxCart.Models.ProductAddedToCartPopupDialogModel model that can be used for this purpose?  It seems like most of the other required fields exist here (ProductName, UnitPrice, Quantity) so hopefully there is an option for the product SKU that I'm overlooking.

Other info -
Plugins package version - NopUltimateThemeCollection_3.9.516.24125
Theme in use - Brooklyn

Thanks for any replies in advance.
