puppeteer-fx TypeError : Click is not a fiunction

[bbandla]

• Puppeteer version:1.12.2
• Node.js version:v11.6.0

I am trying to get puppeteer-fx to work, code below is launching the firefox browser, but i get the TypeError: scope.context.currentPage.click is not a function. Works in Chrome, no issues.
Looks like its not including puppeteer with puppeteer-fx during the runtime? Any suggestions please?

const b = process.env.PUPPETEER_BROWSER || 'chrome';
const puppeteer = b === 'firefox' ?
require('puppeteer-fx') : require('puppeteer')

const World = function() {
scope.driver = puppeteer;
scope.context = {};
};

await scope.context.currentPage.goto(CREDS.url);
await scope.context.currentPage.click(loginpage.loginfields.USERNAME_SELECTOR);
