How to open other application from my application

I am writing code to launch other applications from my react native application for android and ios.

Using Linking form react native I am able to redirect to Play Store/App Store but

How can I launch App if it's already installed?

* I am getting the list of the app's from server

Linking.openURL('https://play.google.com/store/apps/details?id=com.example.myapp&hl=en')

Is there any way that I can launch the app if it's installed else redirect to App store/play store with respect to the platform?
