How to get Webview URL from AccessibilityNodeInfo

Question

Suppose I am in a third-party application, say Amazon.

Now I can get access to all the content of the window using the Availability service and the type of access to the event: typeViewFocused.

And I have a condition that if the contents of the window contain the class name android.webkit.WebView, then I must find the loaded URL for this Webview. But could not find the url, I can access all the content inside the webview, but I do not need the WebView content. I only need the URL that this webview used to download content. Even I checked all AccessibilityNodeInfo objects, but could not find the URL
