Accesing enum type from another script

Hello again :)

I am currently trying to get an enum type from another script. I am trying to get it via Raycast.

My problem at the moment is that i declared the enum in the script to acces it, but now it wants me to declare the variable in the inspector rather than getting it from the raycasthit. Which I understand, but I just don't know how to change that.

I'd be thankful for everyone able to tell me how I can acces the enum type before my switch statement :)

This is the script:

 using UnityEngine;
 using System.Collections;
 
 public class Pickup : MonoBehaviour {
 
     Camera mainCam;
     Collider other;
     public Inventory inventory;
     public ItemType type;
 
     void Start(){
         mainCam = GetComponent<Camera>();
     }
 
     void  Update (){
         int x = Screen.width / 2;
         int y = Screen.height / 2;
         RaycastHit hit;
         Ray ray = mainCam.ScreenPointToRay(new Vector3(x, y,0));
         Debug.DrawRay (ray.origin, ray.direction * 10, Color.yellow);
         
         
         if (Input.GetMouseButtonUp(0) && Physics.Raycast(ray, out hit, 50) && hit.collider.gameObject.tag == "item") {
 
             hit.collider.gameObject.GetComponent<Item>(ItemType);
 
             switch(type){
                 case ItemType.STUHL:
                     Destroy(hit.transform.GetComponent<Collider>());
                     hit.transform.gameObject.active = false;
                     inventory.AddItem(hit.collider.gameObject.GetComponent<Item>());
                     break;
                 case ItemType.PAPIER:
                     Debug.Log("Papier!");
                     break;
             }
         }
     }
 }
