controlling objects with a character controlled by a nav mesh agent

I'm trying to control objects(like cubes) in my game and move around with them using a 3rd person character controlled by a nav mesh agent. The main objective is to be able to some extent grab onto a cube(or make the cube stick to player when he interacts with it) and move around with it and at the end deposit the cube behind a truck. When the player holding the cube interacts with the truck(behind the truck) as he deposits, the cube should be destroyed or hidden for optimisation purposes. As I said before my player is controlled by a nav mesh agent and has a capsule col & rigidbody attached and I have a Interaction script currently attached to other objects in which the player picks up/collects and those items hide and show up in my inventory slots. but unlike what I'm trying to achieve these items are not movable. Thanks in advance I hope I was understandable. Heres the relevant code:

[Code=CSharp]

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.AI;
 
 [RequireComponent(typeof(NavMeshAgent))]
 public class PlayerMotor : MonoBehaviour
 {
 
     Transform target;           //Target to follow
     NavMeshAgent agent;         //Referance to agent
     // Use this for initialization
     void Start()
     {
         agent = GetComponent<NavMeshAgent>();
     }
 
     void Update()
     {
         if(target != null)
         {
             agent.SetDestination(target.position);
             FaceTarget();
         }
     }
 
     public void MoveToPoint(Vector3 point)
     {
         agent.SetDestination(point);
     }
 
     public void FollowTarget(Interactable newTarget)
     {
         agent.stoppingDistance = newTarget.radius * .8f;
         agent.updateRotation = false;
 
         target = newTarget.interactionTransform;
     }
 
     public void StopFollowingTarget()
     {
         agent.stoppingDistance = 0f;
         agent.updateRotation = true;
 
         target = null;
     }
 
     void FaceTarget()
     {
         Vector3 direction = (target.position - transform.position).normalized;
         Quaternion lookRotation = Quaternion.LookRotation(new Vector3(direction.x, 0f, direction.z));
 
         if(direction != Vector3.zero)
         {
             transform.rotation = Quaternion.Slerp(transform.rotation, lookRotation, Time.deltaTime * 5f);
         }
 
     }
