Problem with format () in an Electron app

I'm trying to make an app in Electron js but the url doesn't load. The problem is in the format () function which appears strikethrough. It is apparently deprecated (@deprecated -- since v11.0.0 - User the WHATWG URL API). I need help!

...

app.on('ready', function() {
    mainWindow = new BrowserWindow({});
    
    mainWindow.loadURL(url.format({
        pathname: path.join(__dirname, 'mainWindow.html'),
        protocol: 'file:',
        slashes: true
    }));
});
