How to pass the dynamic prefab of the main player to another script (Photon Pun)?

Question

C++ / C#

Hello.
There is an object (Game Manager) with a script on it (GameManager.cs).
GameManager.cs spawns a player with a prefab:

using Photon.Pun;
using Photon.Realtime;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class GameManager : MonoBehaviourPunCallbacks
{
    public GameObject PlayerPrefab;

    void Start()
    {
        Vector3 pos = new Vector3(Random.Range(-3f, 3f), Random.Range(-3f, 3f));
        PhotonNetwork.Instantiate(PlayerPrefab.name, pos, Quaternion.identity);
    }
...
}

There is a camera (Main Camera), on it the script CameraController.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraController : MonoBehaviour
{

    public GameObject PlayerPrefab;

    [SerializeField]
    private float speed = 2.0F;

    public Vector3 offset;

    [SerializeField]
    public Transform target;

    private void Awake()
    {
        //if (!target) target = FindObjectOfType<Тут надо найти копию префаба/объекта игрока, который заспавнился, которым будем управлять>().transform;
    }

    private void Update()
    {
        Vector3 position = target.position + offset;
        position.z = -10.0F;
        transform.position = Vector3.Lerp(transform.position, position, speed * Time.deltaTime);
    }

}

You need to somehow pass the dynamic prefab to the script that is on the camera (PlayerPrefab / target), so that the camera is above the player who controls the character.
How to do it?
