We are creating our first Ionic app (v4). It will be available on both app stores. I want to make sure we provide all the correct legal notifications, and I have the Ionic MIT notice (https://github.com/ionic-team/ionic/blob/master/LICENSE). Do I need to include license info for any other library that Ionic may use in the app, such as Angular, Cordova, etc.? If so, how can I discover all the libraries that need I need to acknowledge?
