SceneManager.sceneLoaded Cannot Implicityly convert type int to...

Hey everyone.

I have a script that is being used to run my menus and character selection. The intention is to use

 //Checks player one's character
     //Spawns selected character
 void SpawnP1()
     {
         if(P1Char == "CharOne")
         {
             GameObject character = Instantiate(Char1, SpawnA.position, SpawnA.rotation);
         }
     }
 
 //Calls the character spawn script for player one
     void OnEnable()
         {
             SceneManager.sceneLoaded += SpawnP1();
         }

Problem is it is giving me an error: "Cannot implicitly convert type 'void' to 'UnityEngine.Events.UnityAction < UnityEngine.SceneManagement.Scene, UnityEngine.SceneManagement.LoadSceneMode >'"

Maybe because my "SpawnP1()" function is void? Switc$$anonymous$$ng it to public doesn't do the trick. I'm sure it has to be me using it incorrectly, but the documentation on "OnEnable" and "SceneManager.sceneLoaded" are a little sparse.

Thoughts?
