如何在WKWebView中禁用复制和粘贴(标注/弹出)？

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate, WKUIDelegate {
    
    var webView: WKWebView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let configuration = WKWebViewConfiguration()
        configuration.preferences.javaScriptEnabled = true
        
        webView = WKWebView(frame: view.bounds, configuration: configuration)
        webView.navigationDelegate = self
        webView.uiDelegate = self
        
        view.addSubview(webView)
        
        let url = URL(string: "https://example.com")
        let request = URLRequest(url: url!)
        webView.load(request)
    }
    
    // WKNavigationDelegate
    func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        if navigationAction.navigationType == .other {
            let request = navigationAction.request
            let url = request.url?.absoluteString
            
            // 判断是否是复制或粘贴相关的操作
            if url?.contains("copy") == true || url?.contains("paste") == true {
                // 禁止执行复制和粘贴操作
                decisionHandler(.cancel)
                return
            }
            
            // 允许其他请求
            decisionHandler(.allow)
        } else {
            // 允许正常跳转
            decisionHandler(.allow)
        }
    }
    
    // WKUIDelegate
    func webView(_ webView: WKWebView, shouldPreviewElement elementInfo: WKPreviewElementInfo) -> Bool {
        // 禁止预览元素
        return false
    }
    
    func webView(_ webView: WKWebView, shouldPreviewActionItems actionItems: [WKPreviewActionItem]) -> Bool {
        // 禁止弹出操作
        return false
    }
}
