How do I make my PickUp system for my guns have a smooth animation when you pick it up? (PickUp System script below)

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class GrapplePickUpController : MonoBehaviour { public GrapplingGun gunScript; public GrapplingRope grapplingRopeScript; public Rigidbody rb; public BoxCollider coll; public Transform player, gunContainer, fpsCam;

 public float pickUpRange;
 public float dropForwardForce, dropUpwardForce;

 public bool equipped;
 public static bool slotFull;

 private void Start()
 {
     //Setup
     if (!equipped)
     {
         grapplingRopeScript.enabled = false;
         gunScript.enabled = false;
         rb.isKinematic = false;
         coll.isTrigger = false;
     }
     if (equipped)
     {
         grapplingRopeScript.enabled = true;
         gunScript.enabled = true;
         rb.isKinematic = true;
         coll.isTrigger = true;
         slotFull = true;
     }
 }

 private void Update()
 {
     //Check if player is in range and "E" is pressed
     Vector3 distanceToPlayer = player.position - transform.position;
     if (!equipped && distanceToPlayer.magnitude <= pickUpRange && Input.GetKeyDown(KeyCode.E) && !slotFull) PickUp();

     //Drop if equipped and "Q" is pressed
     if (equipped && Input.GetKeyDown(KeyCode.Q)) Drop();
 }

 private void PickUp()
 {
     equipped = true;
     slotFull = true;

     //Make weapon a child of the camera and move it to default position
     transform.SetParent(gunContainer);
     transform.localPosition = Vector3.zero;
     transform.localRotation = Quaternion.Euler(Vector3.zero);
     transform.localScale = Vector3.one;
     

     //Make Rigidbody kinematic and BoxCollider a trigger
     rb.isKinematic = true;
     coll.isTrigger = true;

     //Enable script
     gunScript.enabled = true;
     grapplingRopeScript.enabled = true;
 }

 private void Drop()
 {
     equipped = false;
     slotFull = false;

     //Set parent to null
     transform.SetParent(null);

     //Make Rigidbody not kinematic and BoxCollider normal
     rb.isKinematic = false;
     coll.isTrigger = false;

     //Gun carries momentum of player
     rb.velocity = player.GetComponent<Rigidbody>().velocity;

     //AddForce
     rb.AddForce(fpsCam.forward * dropForwardForce, ForceMode.Impulse);
     rb.AddForce(fpsCam.up * dropUpwardForce, ForceMode.Impulse);
     //Add random rotation
     float random = Random.Range(-1f, 1f);
     rb.AddTorque(new Vector3(random, random, random) * 10);

     //Disable script
     gunScript.enabled = false;
     grapplingRopeScript.enabled = false;
 }

}
