Instantiate connected prefab inside a hierarchy of GameObjects

Hi! I am trying to instantiate a prefab through PrefabUtility.InstantiatePrefab( ). After instantiating the object, I want to set it as a child of a certain GameObject in my scene's hierarchy. I can do it in editor manually, but I cannot find a proper way to do it through code.
In previous versions, I could do something like:

PrefabUtility.DisconnectPrefabInstance(prefabInstance);
prefabInstance.transform.SetParent(newParent);
PrefabUtility.ReconnectToLastPrefab(prefabInstance);

But these PrefabUtility methods are deprecated from 2018.3

Any ideas? Thank you very much!

 

[Update]
I found out that if I modify the instance returned by PrefabUtility.InstantiatePrefab() changes are not really set in scene. But if I wait a couple of seconds and I try to do the very same modifications, these are applied. So, as far as I can understand, there should be some callback telling me: "ok, now you can apply modifications to the instance in scene". Any ideas? Thanks again!

 

Thank you very much, this is exactly what I was looking for.
