How to listen to "beforeNavigate" event in safari app extensions

Question

I'm developing a safari app extension. I've to listen to "beforeNavigate" event as in old Safari JS Extensions, we could listen to these events using Safari's Windows & Tabs API.

I went through the How to create Safari App Extension, but unfortunately couldn't find anything related to these events there.

Can anybody please help me with similar APIs for Safari App Extensions as we had in old Safari JS Extensions.

Starting Safari 13, Apple added an API for page navigation notifications.

In your SafariExtensionHandler.swift, you can now override func page(_ page: SFSafariPage, willNavigateTo url: URL?).
