How to make camera follow in between cursor and player

Hello and just a quick note that I'm quite new to unity and coding, if possible please explain simply. I'm making a topdown shooter and I want to make the camera follow in between the player and the cursor, but I don't know how. I've already made the player movement and player rotating towards the cursor. Here is my Player movement script:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class playerMovement : MonoBehaviour
 {
     public float moveSpeed = 5f;
     public Rigidbody2D rb;
     Vector2 movement;
     Vector2 mousePos;
     public Camera cam;
 
     void Update()
     {
         movement.x = Input.GetAxisRaw("Horizontal");
         movement.y = Input.GetAxisRaw("Vertical");
 
 
         mousePos = cam.ScreenToWorldPoint(Input.mousePosition);
     }
 
     void FixedUpdate()
     {
         rb.MovePosition(rb.position + movement * moveSpeed * Time.deltaTime);
 
         Vector2 lookDir = mousePos - rb.position;
         float angle = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg;
         rb.rotation = angle;
     }
 
 
 
 }

Sorry if my English is bad.
