Ioni 4 open external app

#1

Hi,
I’m trying to open an application from a button in my app, I’ve read in several posts that using the InAppBrowser plugin like ( this.iab.create (‘com.app_package’, ‘_system’) ) should open the application, however the only thing I get with this is the browser answering localhost/com.app_package.

Any idea how I can open for example twitter?
I have also tried the url schema like ( twitter:// ) but I can not open the app on android, on iOS I have not tried it yet.
