How to gameobject.findwithtag tilemap in a different scene?

My scene has 2 scenes. My camera is on the first scene and my tilemap is on the second scene. How do I reference my tilemap to my camera inspector across scenes?

Doesn't work

Code (CSharp):

1. public class CameraFollow : MonoBehaviour
2. {
3.     [SerializeField]
4.     private Tilemap tilemap;
5.  
6.     private void Awake()
7.     {
8.         Tilemap tilemap = (Tilemap)FindObjectOfType(typeof(Tilemap));
9.     }
10. }
