label_desc: Use image node_id 1 to create a new ManagedCollisionCollectionAwaitable object from inherited base classes: LazyAwaitable with example: obj = ManagedCollisionCollectionAwaitable(awaitables_per_sharding, features_per_sharding, embedding_names_per_sharding, need_indices, features_to_permute_indices)
