Appium only shows NATIVE_APP context on a Cordova App

I’m running Appium on MacOS to test a Ionic (mobile app framework) app on an iOS Simulator.

When I execute the following code:

Set<String> text =  ((IOSDriver) driver).getContextHandles();

It only returns one context, NATIVE_APP instead of arrays with multiple context [NATIVE_APP and WEBVIEW]. Any help would be greatly appreciated.
