Can you subscribe to InAppBrowser Events from browser?

Ionic Framework ionic-v3

So, I’m trying to use the InAppBrowser in a browser but I keep getting an undefined message for subscribing to events.

I’m wondering if this is only available on an Anroid/iOS device?

const browser: InAppBrowserObject = this.theInAppBrowser.create(this.Url, “_blank”, options);

browser.on(‘beforeload’).subscribe(event =>
{
console.log(“beforeload -->”,event);
});
