How do you update the static mesh’s material like you would in the editor? Below is current implementation.
I don’t see in the API docs on where to do this.

         import unreal
        
        EAS = unreal.get_editor_subsystem(unreal.EditorActorSubsystem)
        actor_class = unreal.StaticMeshActor
       actor = EAS.spawn_actor_from_class(actor_class, unreal.Vector(), unreal.Rotator())
       mesh = unreal.EditorAssetLibrary.load_asset('/Game/Assets/testAsset.fbx')
       actor.static_mesh_component.set_static_mesh(mesh)
