Electron上でseleniumが実行できない。session not created: No matching capabilities found

ここのサイト
にも同様の質問がされていますが、

公式のサイトのWebDriverJsを参考にして、Electron上でSeleniumを実行したいのですが、以下のエラーが出てElectronが起動しません。

Electron: 10.1.1.
ChromeDriver 85.0.4183.84

ソースコードはhttps://github.com/electron/electron-quick-startのmain.jsにseleniumのコードを加えただけです。

導入はhttps://www.electronjs.org/の公式にあるように、

# Quick Start リポジトリを clone する
$ git clone https://github.com/electron/electron-quick-start

# リポジトリに移動
$ cd electron-quick-start

# 依存ライブラリをインストールし、実行
$ npm install 

$ npm start

に従いました。

なお、seleniumを加えた追加箇所のコード(main.js)は

main.JS
// Modules to control application life and create native browser window
const { app, BrowserWindow } = require("electron");
const path = require("path");


const webdriver = require("selenium-webdriver");

function createWindow() {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, "preload.js"),
    },
  });

  // and load the index.html of the app.
  mainWindow.loadFile("index.html");

  // Open the DevTools.
  // mainWindow.webContents.openDevTools()

///////////////////////////加えたselenium部分//////////////////////////////////
  const driver = new webdriver.Builder()
    // The "9515" is the port opened by chrome driver.
    .usingServer("http://localhost:9515")
    .withCapabilities({
      chromeOptions: {
        // Here is the path to your Electron binary.
        binary:
          "/Users/s_o813/Desktop/Electron/quick/electron-quick-start/node_modules/electron/dist/Electron.app/Contents/MacOS/Electron",
      },
    })
    .forBrowser("electron")
    .build();

  driver.get("http://www.google.com");
  driver.findElement(webdriver.By.name("q")).sendKeys("webdriver");
  driver.findElement(webdriver.By.name("btnG")).click();
  driver.wait(() => {
    return driver.getTitle().then((title) => {
      return title === "webdriver - Google Search";
    });
  }, 1000);
}

app.whenReady().then(() => {

    // On macOS it's common to re-create a window in the app when the
    // dock icon is clicked and there are no other windows open.
