Checkpoint after fall on a plane

Hi! I'm creating a simple game on Unity and trying to implement a checkpoint/respawn system.

The idea is that if the player fall from a specific plane, he will $$anonymous$$t a invisible plane and then trigger a collision event, that will move its position to the respawn one.

I've developed the following code for the collider:

 public class LimiteController : MonoBehaviour {
  public Transform respawnPosition;
  public GameObject Jogador;
  
  void Start()
  {
  respawnPosition.position = GameObject.FindGameObjectWithTag("Respawn").transform.position;
  }
  
  
  void OnTriggerEnter (Collider other)
      {
          if  (other.gameObject.tag == "Limite")
          {
              Jogador.transform.position = respawnPosition.position;
          }
      }
 
 }

I've also attached a Mesh collider and a Rigid body to the limit plane, but still I can't get it to work, someone can help me?
