You can parent it by specifying a
LifetimeScope object before loading the scene.
LifetimeScope is a GameObject, so you can also search from the scene.
Often, you may want to add additional Registers to the loaded scenes.
For example, when context is finalized after assets are loaded asynchronously.
In that case you could use:
LifetimeScope can be serialized by specifying the type of parent.
In base scene.
In additional scene.
When the scene becomes "isLoaded" state, an error will occur if the Parent Type set in the inspector is not found.
