'WKWebView' has no member 'underPageBackgroundColor'

I'm having an issue with trying to build a file I downloaded from PWABuilder. The error I'm getting is: Value of type 'WKWebView' has no member 'underPageBackgroundColor'

Heres the snippet:

if #available(iOS 15.0, *), adaptiveUIStyle { themeObservation = OVATION.webView.observe(\.underPageBackgroundColor) { [unowned self] webView, _ in currentWebViewTheme = OVATION.webView.underPageBackgroundColor.isLight() ?? true ? .light : .dark self.overrideUIStyle()

As I downloaded it from PWABuilder, it should just build fine, so not sure why I'm getting this error. I don't know swift, so not entirely sure why it's happening. I've followed the article here but doesnt make any mention. Any thoughts would be great.
