UE4: When does the Unreal Engine access file system to load actor assets (mesh, sounds, etc) if you spawn a new actor at runtime?

I have a class derrived from AActor which has properties like Meshes, etc. The meshes is a separate assets in content folder which assigned to this properties. I spawn my actors at runtime using SpawnActor function. When my meshes will be loaded? During the spawn, after the spawn or at game loading? I found the Actor Lifecycle documentation https://docs.unrealengine.com/4.27/en-US/ProgrammingAndScripting/ProgrammingWithCPP/UnrealArchitecture/Actors/ActorLifecycle/ but I can't find answer to my question in it. I see that serialized to level actor will be loaded when the level loaded. But what is about spawned at runtime actors?
