Convert Contact URL to Resource Name for People API using Google Apps Script

This is a sample script for converting a contact URL of “person/c###” to a resource name “people/c###” for People API using Google Apps Script.
When you open each contact at Contacts with your browser, you can see the URL like https://contacts.google.com/person/c###################.
Here, you might have a situation where you are required to retrieve the resource name for People API from this URL. But, in the current stage, person/c################### cannot be directly used as the resource name people/c###################. In this report, I would like to introduce a sample script for converting from person/c################### to people/c###################.
