Unity3D 2018.3 Editor script to find PhysX CCD problems

PhysXCCDEditorHelper.cs

////////////////////////////////////////
// Find PhysX components that will trigger the Unity 2018 complaint about
// kinematic with Continuous Collision Detection:
//
//  ERROR: [Physics.PhysX] RigidBody::setRigidBodyFlag: kinematic bodies with CCD enabled are not supported! CCD will be ignored.
//
// Use the script to find troublesome components in the scene or in the project
// then manually change them to a valid value, likely ContinuousSpeculative
//
// See https://docs.unity3d.com/ScriptReference/CollisionDetectionMode.ContinuousSpeculative.html

How to use it?

where to use it please ?
