plugin was registered to receive it when used Cordova with
registerForActivityResult
# Bug Report
In the existing code we are using Cordova with startActivityForResult(), as
part of third party plugin update we are using registerForActivityResult().
I am looking for an example of Cordova with registerForActivityResult()
