Trace a visible ray between two NavMeshAgent (Raycast)

Hi everyone,

I appreciate the new functionnality of Unity for Navmesh and Pathfinding.

Currently,I know how to use NavMesh Agent and deplace a gameobject toward another gameobject.

Now, I want to trace a visible ray, a trace, between these two agents, like in a GPS. In the documentation, I see this function NavMeshAgent.Raycast but I don't know how to use it.

 public class TestNavScript : MonoBehaviour { 
 
     public Transform target; 
         private NavMeshAgent NavComponent;
          private NavMeshHit hit;
 
     // Update is called once per frame
      void Update () {
        GetComponent<NavMeshAgent>().destination=target.position;
     
        GetComponent<NavMeshAgent>().Raycast(target.position,out hit); 
     }
 
 }

After, I will put a mesh on this ray.

Can you help me, please?
