I am working on a main menu, but I am having a problem where the game scene takes too long to load so I want to use async to load the scene on start.

From there when the user selects the ui button to take them to the game scene i want to set syncOperation.allowSceneActivation to true. Here is the code

    public class LoadScenes : MonoBehaviour
    {
        void Start()
        {
            StartCoroutine(LoadScene());
        }
        IEnumerator LoadScene()
        {
            yield return null;
            AsyncOperation asyncOperation = SceneManager.LoadSceneAsync("Forest Map");
            asyncOperation.allowSceneActivation = false;
            while (!asyncOperation.isDone)
            {
                if (asyncOperation.progress >= 0.9f)
                {
                    asyncOperation.allowSceneActivation = true;
                }
            yield return null;
            }
        }
    }
