Dismiss authorize() webview and return focus to the App programatically

Is there a way to programatically dismiss the webview that pops up when calling authorize()?
There is a 'Cancel' button to close the authorize() webview but is there a way to do this programatically?

The issue concerns the authorize() webview and its Cancel button; begin by tracing how authorize() presents and dismisses that webview. Determine whether programmatic dismissal can return focus to the app, and consider the work complete when this behavior is supported or clearly documented as unavailable.
