How to create tunnels/cylinders between lat long points in cesium?

Say I have 6 latitude longitude points that form a polyline that is above the ground. I want to create what looks like a tunnel where there are cylinder(s) or some kind of “buffered radius” around the polyline such that it looks like a worm/tunnel/snake instead of just a polyline. Is this possible in Cesium?

We call these polyline volumes in Cesium. Here’s an example that should give you everything you need to do what you want:

Matt, you are the best.
