when i removed cordova-plugin-inappbrowser after the installation openURL function doesn’t work

cordova plugin remove cordova-plugin-inappbrowser

Hi, I try to use InAppBrowser plugin with cordova, i want to open internal browser in my app, so i use this to achieve my aim:
Firstly, i installed the plugin by typing this

cordova plugin add cordova-plugin-inappbrowser

Then i wrote this method which i call by button click

visitMyWebsite() {
     //cordova.InAppBrowser.open('http://apache.org', '_blank', 'location=yes'); // this works
     openURL('https://google.com'); // this doesn't work
  }

If i call cordova.InAppBrowser.open directly this works, but not happens if i call openURL after i installed this plugin, where i was wrong and how can i fix it?
