title: Open new instance of InAppBrowser in Ionic
body: <p>This is regarding <code>cordova-plugin-inappbrowser</code></p>
  <p>How to create new instance of In-AppBrowser each time it creates? As per the documentation, <code>create</code> method will opens a URL in a new InAppBrowser instance, the current browser instance, or the system browser.</p>
  <p>I want to opens a URL in a new InAppBrowser instance every-time.</p>
  <p>I have tried different initialisations as below, But in both cases it seems using existing instance after first time load. In addition to that I have clear cache in the options.</p>
  <pre><code>import {InAppBrowser} from '@ionic-native/in-app-browser';
  constructor(private iab: InAppBrowser)
  
  // use global instance
  showGlobleBrowser(){
  let browser = this.iab.create(payURL, '_blank', {inapp browser options here...});
  }
  
  // use new instance
  showNewBrowser(){
  let browser = new InAppBrowser().create(contactUsUrl, '_blank',{inapp browser options here...});
  }
  </code></pre>
