How to use the @wdio/logger function in @wdio/logger

import { sum, includes } from 'lodash';
import logger from '@wdio/logger';
import UIElement, { ELEMENT_CMDS, getElementFromResponse } from './element';
import { keys, toPairs } from 'lodash';
import WebDriverProtocol from '@wdio/protocols/protocols/webdriver.json';
import JsonWProtocol from '@wdio/protocols/protocols/jsonwp.json';
import MJsonWProtocol from '@wdio/protocols/protocols/mjsonwp.json';
import AppiumProtocol from '@wdio/protocols/protocols/appium.json';

const log = logger('web2driver');

const DIRECT_CONNECT_PREFIX = 'directConnect';
let DIRECT_CONNECT_CAPS = ['Protocol', 'Host', 'Port', 'Path'];
DIRECT_CONNECT_CAPS = DIRECT_CONNECT_CAPS.map(c => `${DIRECT_CONNECT_PREFIX}${c}`);
const PREFIXED_DIRECT_CAPS = DIRECT_CONNECT_CAPS.map(c => `appium:${c}`);

export default class Session {

  constructor (wdSessionClient) {
    this.client = wdSessionClient;
    this.updateConnectionDetails();
  }

  updateConnectionDetails () {
    // if the remote end has given us a direct url to use different than the
    // one we used to instantiate the session, make sure we use that instead

import logger from '@wdio/logger'
const log = logger('gulp-webdriver')
const colors = require('ansi-colors')
const { series } = require('gulp')

    dist: 'lib',
    test: 'test',
    errorHandler: (title) => {
        return (err) => {
            if (err) {
                log.error(`${colors.red([title]) + err.toString()}`)
            } else {
