Redirect from in-app-browser to Google Chrome on Android using JavaScript

Question

I'm trying to redirect users from the SnapChat browser to Google Chrome when using an Android Phone.

I have followed the instructions recommending I use this:

Phonegap - How to open external link inside the app

<a href="#" onclick="window.open('https://www.google.com', '_system')">

This follows the link, but keeps me in the in-app-browser.

Further research, however, shows me that '_sytem is relegated just to Cordova etc.

Any suggestions as to how to exit to Google Chrome?

I followed JS - Mobile - Open Safari from any browser and was able to do this successfully on iOS to Safari.
