Help with moving AI object to nearest spawned objects position

Hi all, I have characters in my game in hieracy named "jiji_standard" (game is 2D portrait). I have food that randomly spawns with tag "food".

What I want to do is have the nearest character to the food that spawned move to it and then collect it (i will use ontrigger enter for collecting).

I want this to keep going eg as food spawns the nearest character will go and collect it.

I found this script from another post

 using UnityEngine;
 using System.Collections;
 
 public class find_nearest_food : MonoBehaviour 
 {
     
     float projectileSpeed = 0;
 
     void Update()
     {
         float projSpeed = projectileSpeed * Time.deltaTime;
         FindClosestEnemy();
         //print (FindClosestEnemy().name);
 
     }
     GameObject FindClosestEnemy()
     {
         GameObject[] gos;
         gos = GameObject.FindGameObjectsWithTag("food");
         GameObject closest = null;
         float distance = Mathf.Infinity;
         Vector3 position = transform.position;
         foreach (GameObject go in gos) 
         {
             Vector3 diff = go.transform.position - position;
             float curDistance = diff.sqrMagnitude;
             if (curDistance < distance) 
             {
                 closest = go;
                 distance = curDistance;
             }
 
         }
         return closest;
     }
 }

I'm stuck as how to get the nearest character to move to collect the nearest food.

something like?:

jiji_standard.transform.position = Vector3.MoveTowards(transform.position, closest.position, projSpeed);

please can anybody help or advise, thankyou
