JavaScript is disabled in a WebView by default.

WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

In some versions you may have to do it like this:

WebView browser = new WebView();
WebEngine webEngine = browser.getEngine();
webEngine.setJavaScriptEnabled(true);

To enabled JavaScript create you need to create a configuration parameter for WebView init

struct VideoView: View, UIViewRepresentable {
        func makeUIView(context: Context) -> WKWebView {
            let configuration: WKWebViewConfiguration = WKWebViewConfiguration()
            let preferences: WKWebpagePreferences = WKWebpagePreferences()
            preferences.allowsContentJavaScript = true
            configuration.defaultWebpagePreferences = preferences
            let webView: WKWebView = WKWebView(
                frame: .zero,
                configuration: configuration
            )
            return webView
        }
        
        func updateUIView(_ UIView: WKWebView, context: Context) {
            guard let url = URL("") else {return}
            UIView.scrollView.isScrollEnabled = false
            UIView.load(URLRequest(url: url))
        }
    }
