I need help with TPS controls!

I am making a third-person doom-like game. The one thing I can't figure out is making the camera rotate around the character while making the character rotate it's self so it can move in other directions. I am using a capsule and a box collider.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Move : MonoBehaviour
 {
     public Rigidbody rb;
     public GameObject camera;
     public GameObject player;
     public GameObject graphics;
     public float speed;
     
     // Update is called once per frame
     void FixedUpdate()
     {
         if (Input.GetKey(KeyCode.W))
         {
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y + 1f), player.transform.position.z);
             rb.AddForce(0, 0, speed * Time.deltaTime);
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y - 1f), player.transform.position.z);
         }
         if (Input.GetKey(KeyCode.S))
         {
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y + 1f), player.transform.position.z);
             rb.AddForce(0, 0, -speed * Time.deltaTime);
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y - 1f), player.transform.position.z);
         }
         if (Input.GetKey(KeyCode.A))
         {
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y + 1f), player.transform.position.z);
             rb.AddForce(-speed * Time.deltaTime, 0, 0);
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y - 1f), player.transform.position.z);
         }
         if (Input.GetKey(KeyCode.D))
         {
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y + 1f), player.transform.position.z);
             rb.AddForce(speed * Time.deltaTime, 0, 0);
             graphics.transform.position = new Vector3(player.transform.position.x, (graphics.transform.position.y - 1f), player.transform.position.z);
         }
         if (Input.GetKey(KeyCode.LeftArrow))
         {
             graphics.transform.Rotate(graphics.transform.rotation.x, (graphics.transform.rotation.y - 5f), graphics.transform.rotation.z);
             player.transform.Rotate(player.transform.rotation.x, (player.transform.rotation.y - 5f), player.transform.rotation.z);
         }
         if (Input.GetKey(KeyCode.RightArrow))
         {
             graphics.transform.Rotate(graphics.transform.rotation.x, (graphics.transform.rotation.y + 5f), graphics.transform.rotation.z);
             player.transform.Rotate(player.transform.rotation.x, (player.transform.rotation.y + 5f), player.transform.rotation.z);
         }
     }
 }
