How to Launch application that is already installed on mobile phone from my Ionic Application?

I am developing new IONIC application tat shows list of applications and user can click on one of them. On click, new application will check if the clicked application is installed on device or not. If not, user will be redirected to appropriate platform specific play store where user can install. If yes, application will be launched. I did search and found reference to lampa plugin that address this requirement however, I am unable to use this plugin as it gives undefined error on the startApp.start(…) method’ (rather any method on startApp). For availability of the application on the device, i am using appAvailability ngCordova plugin that works fine. I need help in launching of the ‘clicked application’. Please suggest.
