如何禁用嵌入到WKWebView的youtube视频的自动播放

let script = "var videos = document.querySelectorAll('video'); videos.forEach(video => video.pause());"
webView.evaluateJavaScript(script, completionHandler: nil)

let configuration = WKWebViewConfiguration()
configuration.mediaTypesRequiringUserActionForPlayback = .all
let webView = WKWebView(frame: .zero, configuration: configuration)

class ViewController: UIViewController, WKNavigationDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        let webView = WKWebView(frame: view.bounds)
        webView.navigationDelegate = self
        view.addSubview(webView)
    }
    
    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        let script = "var videos = document.querySelectorAll('video'); videos.forEach(video => video.pause());"
        webView.evaluateJavaScript(script, completionHandler: nil)
    }
}
