I want to create a bookmark function using the toggle button,I want to develop the bookmark function

I want to create a bookmark function that reflects the information to other scenes in real time by clicking the toggle button in the list.

static DataManager m_instance; public static DataManager Instance { get { return m_instance; } }

 public List<Image> images;

I made a list and I want to use it in a script in another scene.

public void Click() { DataManager.Instance.images[0] = GetComponent();

 }

,If you press the toggle button in the list, I want to change in real time that information is entered and deleted in another scene.

static DataManager m_instance; public static DataManager Instance { get { return m_instance; } }

 public List<Image> images;

By making a list of images like this

public void Click() { DataManager.Instance.images[0] = GetComponent();

 }

I would like to import this from another scene and use it
