Welcome to the Cesium community @Karthik_M!

The measurements are not part of the open source CesiumJS. They are available on Cesium ion, using Cesium Stories (see https://cesium.com/docs/tutorials/stories-introduction/). So if you just need to make some distance/height/area measurements, you can upload your data to Cesium ion and use it there.

Let me know if that works for you!
