mouse move rotate object question

So I have two scripts, one is my pickup object script and another is a left click drag object and it rotates script. I would like to know how to implement the rotate action in the rotate script into my pickup object script. I would like it so that I hold down "r" and i can now rotate the object i have picked up in view, around using either mouse movement or left click drag. When I release "r" it goes back to my normal pickup object stuff.

Pickup object script: using System.Collections; using System.Collections.Generic; using UnityEngine;

public class LineOfSight : MonoBehaviour { //we assign this script to the first person character private RaycastHit vision; // this is where ill store the information from the raycast collision public float rayLength; // length of my raycast private bool isGrabbed; // the player is carrying the object private Rigidbody grabbedObject; // ill assign vision to this later as a reference to the objects rigidbody public float throwForce = 1000; // amount of force for throwing the object float rotSpeed = 10;

 void Start()
 {
     rayLength = 4.0f; // set the raycast length from the start
     isGrabbed = false; // game just started so the player is not carrying an object

 }

 void Update()
 {
     // Im using the first person character as my camera position, cast from there in forwards direction, store what I hit into the variable vision, and the raylength is the length of the raycast ray
     if (Physics.Raycast(Camera.main.transform.position, Camera.main.transform.forward, out vision, rayLength)) 
     {
         if(vision.collider.tag == "interactable")// each interactable object has a tag called interactable
         {
             if (Input.GetKeyDown(KeyCode.E) && !isGrabbed) // if I hit E and I am not carrying an object
             {
                 grabbedObject = vision.rigidbody; // assign the object we hit with raycasts rigidbody component to the variable grabbedObject
                 grabbedObject.isKinematic = true; // avoid recognizing collisions
                 grabbedObject.transform.SetParent(gameObject.transform); // set the grabbed object as a child of the camera
                 isGrabbed = true; // set the fact that im carrying something now
             }

             else if (isGrabbed && Input.GetKeyDown(KeyCode.E)) // if i am carrying something and I hit E, drop the object
             {
                 grabbedObject.transform.parent = null; //detach from parent
                 grabbedObject.isKinematic = false; // turn collision detection on
                 isGrabbed = false; // set it so im not shown as carrying anything so that I can hit E again and pick it back up
             }
             else if (isGrabbed && Input.GetKey(KeyCode.R))
             
             if (Input.GetMouseButtonDown(1)) // if i click right mouse button
             {
                 grabbedObject.isKinematic = false; // bring back collision detection
                 grabbedObject.transform.parent = null; // remove from parent
                 isGrabbed = false; // set it so im not carrying anything so i can click E and pick up again
                 grabbedObject.AddForce(Camera.main.transform.forward * throwForce); // using the objects rigidbody, add force to it in forward direction
             }
             


         }
     }
     

     
 }
 

}

rotate object script:

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

public class myRotate : MonoBehaviour { float rotSpeed = 10;

 void OnMouseDrag()
 {
     float rotX = Input.GetAxis("Mouse X") * rotSpeed * Mathf.Deg2Rad;
     float rotY = Input.GetAxis("Mouse Y") * rotSpeed * Mathf.Deg2Rad;

     transform.RotateAround(Vector3.up, -rotX);
     transform.RotateAround(Vector3.right, rotY);
 }

}
