How to Change the position of a tile to the player position?

Hello everyone,

I want to make my character pick up a tile when clicked on it. I was able to print the coordination of the tile I'm clicking on but I couldn't make it move to the player position. Here is the code I did so far:

 using UnityEngine;
 using UnityEngine.Tilemaps;
 
 public class MouseManager : MonoBehaviour
 {
 
 private Tilemap tilemap;
 private Transform playerPos;
 
 
 
 void Start()
 {
     //You can serialize this and assign it in the editor instead
     tilemap = GameObject.Find("Tilemap_Ground").GetComponent<Tilemap>();
     playerPos = GameObject.FindGameObjectWithTag("Player").transform;
 }
 
 void Update()
 {
     if (Input.GetMouseButtonDown(0))
     {
         Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
         Vector3Int gridPos = tilemap.WorldToCell(mousePos);
         Sprite spr = tilemap.GetSprite(gridPos);
 
 
         if (tilemap.HasTile(gridPos))
             Debug.Log(gridPos);
             
           
            
 
 
              
             
             
           
     }
 }
 
 }
