In your WKNavigationDelegate implementation, you can do something like the following:

    func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
      if let url = navigationAction.request.url, url.scheme == "tel" {
        UIApplication.shared.open(url)
        decisionHandler(.cancel)
      }else {
        decisionHandler(.allow)
      }
    }
