How can I destroy a GameObject after a scene is loaded?

Hi, I’m having a hard time with this issue, currently I have Timer as the top layer inside it is the text and the image for my timer. i use dontDestroyOnLoad for my timer to pass through some scenes that needed a timer, but when I loaded the main menu the timer is still there. how can i destroy a GameObject that has dontDestroyOnLoad attached to it?

Add this to the script in the Timer gameobject:

void OnEnable()
{
	SceneManager.sceneLoaded += OnSceneLoaded;
}

void OnDisable()
{
	SceneManager.sceneLoaded -= OnSceneLoaded;
}

private void OnSceneLoaded(Scene scene, LoadSceneMode mode)
{
	// here you can use scene.buildIndex or scene.name to check which scene was loaded
    if (scene.name == "MainMenu"){
    	// Destroy the gameobject this script is attached to
        Destroy(gameObject);
	}
}
