How to Access .PDF downloadable files in inapp browser ionic3

Hello ionic community ! I wrapped a website using Inappbrowser and it has .pdf downloadable files which i couldn’t access.I tried almost every method here present in ionic community and i couldn’t find any proper solution till now for this particular method.

  export class HomePage {
  constructor(private iab: InAppBrowser,public platform: Platform) {
  platform.ready().then(() => {
  let browser = this.iab.create(' url ','_blank',{zoom:'yes',location:'no'});;


Does anyone have any solution to this method and am new to ionic frameworks too
I need to figure this out so badly and am doing for android platform :frowning:
