How Do I Make An Object Move In A Set Direction Continuously?

I am moving a player object around an arena with mouse clicks, but the object stops when it gets to the position the mouse was clicked at. How can I make it continue moving even after that? What I am looking for is a "move in the direction of X position" Here's my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class EzrealCode : MonoBehaviour
 {
     [SerializeField] float heartPoints = 6.00f;
     [SerializeField] float manaPoints = 8.00f;
 
     [SerializeField] float speed = 5f;
 
     Vector2 lastClickedPos;
     bool moving;
 
     private void Update()
     {
         
 
         if (Input.GetMouseButtonDown(0))
         {
             lastClickedPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
             moving = true;
         }
 
         if (moving && (Vector2)transform.position != lastClickedPos)
         {
             float step = speed * Time.deltaTime;
             transform.position = Vector2.MoveTowards(transform.position, lastClickedPos, step);
         }
 
         else
         {
             moving = false;
         }
     }
 }
