Zaraz E-commerce tracking

GA4 added to Zaraz and E-commerce tracking is enabled.

Checked zaraz is running in console, all OK, but when I add a zaraz.ecommerce event call to my tag as below, I see an error in the console: ‘zaraz.ecommerce is not a function…’

                zaraz.ecommerce('Product Clicked', {
                  product_id: '1234',
                  sku: '1234',
                  category: 'My Category',
                  name: 'Product Name',
                  price: 123.45,
                  currency: 'GBP',
                  position: 1
