The UIKit view that should be used to expand your background images behind a glass sidebar is called the "Background Extension View." This view allows your content to surface under the sidebar's large glass platter, preserving visual continuity. It is designed to cover the entire width, including the leading safe area inset for the sidebar, and is particularly useful for creating a vibrant and immersive design by extending content like images behind the sidebar.
