What Privilege, etc. is associated with the Product Management Tile added with 25B?

Summary:

After 25B was applied, a new Tile named "Product Management" is displaying under Product Management.
When you click on this new "Product Management" Tile, a page displays which states: Permission is required to view this content.

Per knowledge document KB174886: The new Product Management tile is secured with the opt-in 'Search Items Using New User Interface'. Currently, users with this opt-in can see the tile, but the Redwood Landing Page is only accessible to those with the privilege EGP_ACCESS_LANDING_PAGE_PRIV. Users with custom roles will need to add this privilege to access the page. Without the correct privilege, the page will appear blank, showing this error message.
