-Use the Nested iframes API to subscribe to the nested iframe creation event and access the `CoreWebView2Frame` properties, methods, and events for the nested iframe.
+###### Track navigation history for nested iframes (FrameCreatedEvent API)
 
-By default, for performance, WebView2 doesn't track nested iframes.  WebView2 only tracks a nested iframe if its parent iframe (`CoreWebView2Frame`) has subscribed to the `CoreWebView2Frame.FrameCreated` event.
+The FrameCreatedEvent API supports nested iframes, such as recording the navigation history for a second-level iframe. Without this API, WebView2 only tracks first-level iframes, which are the direct child iframes of the main frame. Using this API, your app can subscribe to the nested iframe creation event, giving the app access to all properties, methods, and events of CoreWebView2Frame for the nested iframe.
 
-For a page that has multi-level iframes, you can choose to track any of the following:
