how to implementing wandering in EnemyAI

Unity Engine
1

Dead community,

Could someone help me out with implementing a wandering if the player is not in range.
because now the enemy will always walk to the player even if he is far away
i don’t have any experience with that

this is what i have so far

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;
using UnityEngine.SceneManagement;

public class AdvanceAI : MonoBehaviour
{

    Transform target;
    [HideInInspector]
    public NavMeshAgent agent;
    Animator anim;
    bool isDead = false;
    public bool canAttack = true;

    [SerializeField]
    float chaseDistence = 2f;

    [SerializeField]
    float turnSpeed = 5f;
    public float DamageAmount = 35;

    [SerializeField]
    float attacktime = 2f;

    void Start()
    {
        target = GameObject.FindGameObjectWithTag("Player").transform;
        agent = GetComponent<NavMeshAgent>();
        anim = GetComponent<Animator>();
    }
    void Update()
    {
        float distance = Vector3.Distance(transform.position, target.position);

        if (!isDead && !PlayerHealth.Singleton.isDead)
        {
            if (distance < chaseDistence && canAttack)
            {
                AttackPlayer();
            }

            else if (distance > chaseDistence)
            {
                ChasePlayer();
            }
        }
        else
        {
            DisableEnemy();
        }
    }

    public void EnemyDeathAnim()
    {
        isDead = true;
        anim.SetTrigger("IsDead");
    }

    void ChasePlayer()
    {
        agent.updateRotation = true;
        agent.updatePosition = true;
        agent.SetDestination(target.position);
        anim.SetBool("IsWalking", true);
        anim.SetBool("IsAttacking", false);
    }

    void AttackPlayer()
    {
        agent.updateRotation = false;
        Vector3 direction = target.position - transform.position;
        direction.y = 0;
        transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(direction), turnSpeed * Time.deltaTime);
        agent.updatePosition = false;
        anim.SetBool("IsWalking", false);
        anim.SetBool("IsAttacking", true);
        StartCoroutine(AttackTime());
    }

    void DisableEnemy()
    {
        canAttack = false;
        anim.SetBool("IsWalking", false);
        anim.SetBool("IsAttacking", false);

    }

    IEnumerator AttackTime()
    {
        canAttack = false;
        yield return new WaitForSeconds(0.5f);
        PlayerHealth.Singleton.DamagePlayer(DamageAmount);
        yield return new WaitForSeconds(attacktime);
        canAttack = true;
    }
}

Is this is your code?
Your first step should be to understand, what this code does first.

I make it with help of a tutorial,
I understand most of it

In line 44, you could add condition, which says, when stop chasing. I.e. out of range. Somehow similar as in line 39.
Then you could add another else statement, telling your bot, to wander about. You could use timer with some randomization, to change direction of wandering.

Don’t get me wrong here but how ?
(im still learning)

This is your good starting point
Getting Started

I don’t know what you know and what not, so you better stick to tutorials for now, until you understand basics.
