InAppBrowser doesn't open in app, always opens system browser


Isn’t it just as simple as doing the following:

import { InAppBrowser } from 'ionic-native';


let browser = new InAppBrowser(url, "_blank");

Tried with _self too. Here it says to add some things in your config.xml, I tried that too but also with no luck, it just keeps opening in the system browser

What’s the trick to make it actually open in the app?
