How to change geolocation settings on WKWebView

We're developing an application using location feature in WKWebView. When accessing a URL that uses location information from WebView, a dialog box saying "<URL> Would Like To Use Your Current Location - Don't Allow or OK". If "Dont allow" is selected multiple times, the dialog will disappear and the location setting for that URL will be fixed as "Don't Allow".

In Safari, I can change that location settings for each URL, But Application's WebView does not have such settings UI. How do I clear or change the setting so that location information is no longer available? It seems that reinstalling the application will clear the WebView location settings.
