Rigidbody2d NPC movement

Hello scripting noob here,

I am trying to make a flying npc that always refers to my Camera and move slightly left and right in a timely manner.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Test : MonoBehaviour {
     // Movement speed
     public float speed = 2;
     public float force = 300;
     public Transform target;
     private Rigidbody2D rb2d;
     // Use this for initialization
     void Start () {
         // Fly towards the right
         //GetComponent<Rigidbody2D>().velocity = Vector2.right * speed;
         rb2d = GetComponent<Rigidbody2D> ();
     }
 
 
 
 
     // Update is called once per frame
     void FixedUpdate () {
         GetComponent<Rigidbody2D>().velocity = Vector2.right * speed;
 
     }
 }
 

Is there a way to target the camera while moving left and right with this character?
