How to attach the Safari Debugger to the simulator in a turbo-ios native app

I want to attach the Safari Debugger to the simulator in a turbo-ios native app. According to this blog post, you need to add the following code

    let webView = WKWebView()
if #available(iOS 16.4, *) {
    webView.isInspectable = true
}

let session = Session(webView: webView)

Unfortunately, the author does not say where to put this code. I have tried to do this in the class SceneDelegate as follows

private let webViewConfiguration: WKWebViewConfiguration = {
    let configuration = WKWebViewConfiguration()
    configuration.applicationNameForUserAgent = " IOS-xyz/1.0"
    // Enable inspection for Safari debugger
    if #available(iOS 16.4, *) {
        configuration.isInspectable = true
    }

but this gives an error

Value of type 'WKWebViewConfiguration' has no member 'isInspectable' 

So where do I put this code?
