How can I get my 2D enemy to rotate to look at my player?

This is the code i have so far

Vector3 dir = player.position - transform.position;

        Quaternion lookRotation = Quaternion.LookRotation(dir);
        Vector3 rotation = lookRotation.eulerAngles;
        enemy.rotation = Quaternion.Euler(0f, 0f, rotation.z);

        if (timeBtwShots <= 0)
        {
            //GameObject Bullet = Instantiate(projectile, Firepoint.position, Quaternion.identity);
            //timeBtwShots = startTimeShots;
            //Destroy(Bullet, 3f);

        }
        else
        {
            timeBtwShots -= Time.deltaTime;
        }

@Charlie010903 I usually take a way to different approach the code is a bit noob like but works very well

`Transform Player;
Quaternion ang_Left;
Quaternion ang_Right;

void Start(){
ang_Left.y = 180;
}

void Update(){
if (Player.position.x - transform.position.x <= 0){
transform.SetPositionAndRotation(transform.position , ang_Left);
}

else{
transform.SetPositionAndRotation(transform.position , ang_Right);
}
}`

for this to make sure your game object is set to y rotation at 0 and is facing right side else change the ang_Left and ang_Right variables

public transform player;
void Start()
{
player = GameObject.FindGameObjectWithTag(“Player”);
}
void Update()
{
transform.LookAt(player);
}
