Hello uttarwarsandesh33, your questions has little to do with this package and answers can be eaisly found on google, but let me help you:

1. API doesn't provide a way to directly read/write the local storage, but it can be done with execute_script:
   let value = await driver.executeScript("return window.localStorage.getItem(arguments[0]);", key)
   or
   driver.executeScript("window.localStorage.setItem(arguments[0], arguments[1]);", key, value)

2. The same way as above - by manipulating it with executeScript.

3. Due to many possible configurations the best way would be to create customDriver.js file in your home directory:

'use strict';
var { Builder } = require('selenium-webdriver');

/**
 * Creates a Selenium WebDriver using Selenium grid with Chrome as the browser
 * @returns {ThenableWebDriver} Selenium web driver
 */
module.exports = function() {

const screen = {
  width: 640,
  height: 480
};

let driver = new Builder()
    .forBrowser('chrome')
    .setChromeOptions(new chrome.Options().headless().windowSize(screen))
    .setFirefoxOptions(new firefox.Options().headless().windowSize(screen))
    .build();
}

and run it with:
node ./node_modules/selenium-cucumber-es6/index.js -s ./step-definitions -b customDriver.js

getting this error while using
let value = await driver.executeScript("return window.localStorage.getItem(arguments[0]);", key)
