Is it possible to execute a method of CustomEditor from another script?

Is it possible to execute a method of CustomEditor from another script?

For example, I have two scripts:
CustomEditor1 is attached to Object1 and CustomEditor2 is attached to Object2.
Then, when the [Add Scripts] button of CustomEditor1 is pressed on Inspector, I would like to also execute the process when the [Update Scripts] button of CustomEditor2 is pressed.
Is this possible?

CustomEditor1 .cs

public class CustomEditor1 : MonoBehaviour
{
}

[CustomEditor(typeof(CustomEditor1))]
public class CustomEditor1Editor : Editor
{
	public override void OnInspectorGUI()
	{
		base.OnInspectorGUI();

		if (GUILayout.Button("Add Scripts"))
		{
			AddScripts();
		}
	}

	public void AddScripts()
	{
		Debug.Log("Add Scripts");
	}
}

CustomEditor2.cs

public class CustomEditor2 : MonoBehaviour
{
}

[CustomEditor(typeof(CustomEditor2))]
public class CustomEditor2Editor : Editor
{
	public override void OnInspectorGUI()
	{
		base.OnInspectorGUI();

		if (GUILayout.Button("Update Scripts"))
		{
			UpdateScripts();
		}
	}

	public void UpdateScripts()
	{
		Debug.Log("Update Scripts");
	}
}
