javascript – The best way to talk from embedded HTML to Swift to alter bool

Howdy I want to change the worth of the binding variable ‘click on’ as soon as the onReady block within the html is executed. I can talk from swift to html by utilizing consider java script. However how do I talk from the onReady within the html to swift to alter the bools val? I attempted making a coordinator class however

struct SmartReelView: UIViewRepresentable {
    let hyperlink: String
    @Binding var isPlaying: Bool
    @Binding var click on: Bool        //variable to be adjustments
    
    func makeUIView(context: Context) -> WKWebView {
        let webConfiguration = WKWebViewConfiguration()
        webConfiguration.allowsInlineMediaPlayback = true
        let webView = WKWebView(body: .zero, configuration: webConfiguration)
        
        loadInitialContent(in: webView)
        
        return webView
    }

    func updateUIView(_ uiView: WKWebView, context: Context) {
        let jsString = "isPlaying = ((isPlaying) ? "true" : "false"); watchPlayingState();"
        uiView.evaluateJavaScript(jsString, completionHandler: nil)
    }
    
    personal func loadInitialContent(in webView: WKWebView) {
        let embedHTML = """
