AppLauncher and IOS

I am trying to use the plugin ‘AppLauncher’ to launch another app. This works fine on the android version but on IOS I get the following error:

'-canOpenURL: failed for URL: “twitter://” - error: “This app is not allowed to query for scheme twitter”

I searched around and it seems like I have to add to the info.plist to allow app schemes to be queried but I am not sure how to do this on Ionic.
