version 7.6.2 Getting started. How to display userid and username of leave requester in the Managers form "Review travel request"

Working through the notes and on page where I build the review form, there are instructions of adding details as below
request.destination, request.departureDate.
Have added request.userId but would like actual name to be displayed. How to achieve this.
Thanks

Hello,
You can use the following REST API to get the complete information on a user:

…/API/identity/user/:userId

Where you’ll plug in request.userId at :userId. You’ll get first name and last name as part of the response in the JSON object. For more information on the REST API see:
