When clicked, more items are loaded and appended to the current page without a full page reload. This type creates a smoother Browse experience, similar to infinite scroll.
Infinite scroll: Automatically loads more items as the user scrolls to the bottom of the page. This type offers the most seamless Browse experience, removing the need for clicks.
