Can you restate the GA4 Enhanced Ecommerce concepts of "view_item_list" and "add_to_cart"?

edit

The concept of "viewitemlist" refers to the action of a user viewing a list of items that are available for purchase on an ecommerce website. This could be a category page, search results page, or any other page where multiple products are displayed.

Similarly, "addtocart" refers to the action of a user adding a particular item to their shopping cart after viewing it on the website. This is a key step in the ecommerce purchase journey, as it indicates a user's intent to purchase a specific item.
