UXP Scripting manual
Help of InDesign says
UXP Scripting
Scripting in InDesign is now powered with the Unified Extensibility Platform (UXP) so that you can use modern JavaScript (ES5 and most of the ES6 features) to automate tasks. Find out more information about UXP Scripting https://developer.adobe.com/indesign/uxp/
And this link goes nowhere. Is there some manual about new scripting?
