Question Help with picking up items with key please

Hi, I am trying to make it so my player picks up an item from the ground when i press the E key, at the moment, the player picks up the item automatically when ran over the item collider. I've been trying to figure out how to do it but I have had no success and end up messing things up, i have the "PlayerMove" script for the main player and a "Pickups" script that is attached to the items and detects when the player collides with them.

PlayerMove Script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.AI;
5. using Cinemachine;
6. public class PlayerMove : MonoBehaviour
7. {
8.     private NavMeshAgent nav;
9.     private Animator anim;
10.     private Ray ray;
11.     private RaycastHit hit;
12.     public GameObject aimObj;
13.     private string axisNamed = "Mouse X";
14.     public GameObject freeCam;
15.     public GameObject staticCam;
16.     private bool freeCamActive = true;
17.  
18.     private float x;
19.     private float z;
20.     private float velocitySpeed;
21.     CinemachineTransposer ct;
22.     CinemachineOrbitalTransposer cot;
23.     private Vector3 pos;
24.     private Vector3 currPos;
25.  
26.     public static bool canMove = true;
27.     void Start()
28.     {
29.         nav = GetComponent<NavMeshAgent>();
30.         anim = GetComponent<Animator>();
31.         cot = staticCam.gameObject.GetComponent<CinemachineVirtualCamera>().GetCinemachineComponent<CinemachineOrbitalTransposer>();
32.         freeCam.SetActive(false);
33.         staticCam.SetActive(true);
34.     }
35.     void Update()
36.     {
37.         x = nav.velocity.x;
38.         z = nav.velocity.z;
39.         velocitySpeed = x + z;
40.  
41.         if (Input.GetMouseButton(0))
42.         {
43.             if(canMove == true)
44.             {
45.                 ray = Camera.main.ScreenPointToRay(Input.mousePosition);
46.                 if (Physics.Raycast(ray, out hit))
47.                 {
48.                     nav.SetDestination(hit.point);  
49.                 }
50.             }
51.         }
52.  
53.         if(nav.remainingDistance <= nav.stoppingDistance)
54.         {
55.             anim.SetBool("Sprinting", false);
56.         }
57.         else
58.         {
59.             anim.SetBool("Sprinting", true);
60.         }
61.  
62.         pos = Input.mousePosition;
63.  
64.         if(Input.GetMouseButton(1))
65.         {
66.             if(Input.GetAxis("Mouse X") > 0)
67.             {
68.                 aimObj.transform.Rotate(0, 75 * Time.deltaTime, 0);
69.             }
70.             if(Input.GetAxis("Mouse X") < 0)
71.             {
72.                 aimObj.transform.Rotate(0, -75 * Time.deltaTime, 0);
73.             }
74.  
75.             if (cot != null)
76.             {
77.                 cot.m_XAxis.m_InputAxisName = axisNamed;
78.             }
79.             if(pos.x != 0 || pos.y != 0)
80.             {
81.                 currPos = pos / 200;
82.             }
83.         }
84.         else
85.         {
86.             if (cot != null)
87.             {
88.                 cot.m_XAxis.m_InputAxisName = null;
89.                 cot.m_XAxis.m_InputAxisValue = 0;
90.             }
91.         }
92.     }
93. }

Pickups Script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Pickups : MonoBehaviour
6. {
7.     public int number;
8.    
9.     void OnTriggerEnter(Collider other)
10.     {
11.         if(other.CompareTag("Player"))
12.         {
13.             InventoryItems.newIcon = number;
14.             InventoryItems.iconUpdate = true;
15.             Destroy(gameObject);
16.         }
17.     }
18. }
