How to find the position of player after they press a certain key

Question

I'm trying to create a script for when an npc goes to a location after the player presses a key within a certain range. I've got the first part down which is having the npc know when the player presses the key. But I still couldn't figure out how to get the npc to find where the player was standing when the key was pressed so that they could then move to that location.

I know that I need some kind of variable to store the coordinates of the player but otherwise I've been stumped for a while. ://

Here's what I have so far:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Move : MonoBehaviour{
     
     [SerializeField]
     private bool player;
 
     private void Update(){
         if (player){
             if (Input.GetKeyDown(KeyCode.F)){
                 player = false;
                 Debug.Log("Person noticed you!");
             }
         }
     }
 
     private void OnTriggerStay2D(Collider2D other){
         if (other.gameObject.tag == "Player"){
             player = true;
         }
     }
 
     private void OnTriggerExit2D(Collider2D other){
         if (other.gameObject.tag == "Player"){
             player = false;
         }
     }
 
 }

I'm still fairly new to coding in C# and Unity, so sorry if the solution was obvious ://

  public class Move : MonoBehaviour{
      
      private Transform player;
      private bool moveTowardsPlayerLocation;
      private void Update(){
          if (player != null && Input.GetKeyDown(KeyCode.F)){
              moveTowardsPlayerLocation = true;
          }
          if(moveTowardsPlayerLocation)
          {
              // Do something like
              // transform.position = Vector3.MoveTowards(transform.position, player.position, Time.deltaTime);
          }
      }
  
      private void OnTriggerStay2D(Collider2D other){
          if (other.CompareTag("Player")){
              player = other.transform;
          }
      }
  
      private void OnTriggerExit2D(Collider2D other){
          if (other.transform == player){
              player = null;
          }
      }
  }
