When listing an app in the App Workbench Settings, you can also enable App Customization. Your users who add an app to their personal App Library will now be able to customize the app.
To customize the app, your users can select the app in the personal App Library, then click the sprocket under the app name.
Users can then modify the App Bundle ID, App Bundle Display Name, App Version, add Custom Configuration Files if the app has the option to use them, and change the App Icon.
