如何在Electronjs中为and视图添加前进、后退和刷新按钮？

const { app, BrowserWindow } = require('electron');

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600
  });

  win.loadURL('https://example.com'); // 加载需要显示的网页地址

  // 添加前进、后退和刷新按钮
  const { webContents } = win;
  const { session } = webContents;
  const { globalShortcut } = require('electron');

  globalShortcut.register('CommandOrControl+Shift+B', () => {
    if (webContents.canGoBack()) {
      webContents.goBack();
    }
  });

  globalShortcut.register('CommandOrControl+Shift+F', () => {
    if (webContents.canGoForward()) {
      webContents.goForward();
    }
  });

  globalShortcut.register('CommandOrControl+Shift+R', () => {
    session.clearCache(() => {
      webContents.reload();
    });
  });
}

app.whenReady().then(createWindow);
