Hey all, I am working in an existing extension for the Cart in the Shopping Application, and I need the TransactionHistory model, which is in the myAccount app. What is the best way to get this into the Shopping Application? If I just 'inject' it into the extension, it throws the 'not found' error in the console. This is a 19.1 site, btw, and customizations are handled through extensions. Thanks for your time!
