How to call the url_scheme of another app with Ionic4?

I have to integrate an Ionic4 app with an external app.
This is an app installed on the same device.
I have to call an url_scheme such as:


I have also to get a return value from this app.
I have to do this on both Android and iOS.
My app uses Cordova plugins.

Which is the right way to do this call?

Thank you very much
