 Search providers can optionally provide light and dark mode gleam icons that are displayed in the search bar when the search provider is currently enabled. When the **DynamicContentEndpoint** element is provided in the app manifest, a request will be sent to the specified URL and the search provider responds with a json file in the format defined below that includes the URLs of the icon image files and other metadata. The gleam icon request will be sent periodically while the search provider is the most recent provider active in Windows Search. The cadence for this request is every 6 hours. A request will also be sent upon each Search launch and on device unlock.
