I am using puppeteer for text extraction in the Angular app. I installed puppeteer using npm. I am using node version 14.7.3 and typescript version 3.9.6 and puppeteer version 11.0.0

I used below code in component.ts file - const puppeteer = require('puppeteer');

I am getting this error in terminal: error TS2304: Cannot find name 'Lowercase'. 6437 export declare type ResourceType = Lowercase<Protocol.Network.ResourceType>

What is the cause of this error? How can I resolve this error? How to include puppeteer library with Angular?
