Difference between _system and _blank in window.oepn

Hello :slight_smile:
I used inappbrowser plugin to implement web view like below

const options : InAppBrowserOptions={
      location:'no',
      clearcache:'yes',
      clearsessioncache:'yes',
      mediaPlaybackRequiresUserAction:'yes',
      hardwareback:'yes'
    }

    const browser = this.inapp.create("http://google.com", "_blank",options)

But I face a problem that a tag is not opening at all.
so I changed _blank to _system and it works. but opened in chrome which is my default internet
How can I open a tag with Cordova webview(I mean on open web on my app)
