How do i use EditorSceneManager.GetSceneManagerSetup / RestoreSceneManagerSetup?

Hello, I want to save the hierarchy of multi scene. After I unload one of the two scenes and play the game in editor, the unloaded scene is automatically removed. I want to not remove the scene automatically. Is there a way to change this setting?

And how do I use EditorSceneManager.GetSceneManagerSetup / RestoreSceneManagerSetup? I tried to serialize Scenesetups into a ScriptableObject. But I can't restore Scenesetups after I play the game in editor. I made a simple sample project for testing. Does anyone know what the problem might be?
