return await attachment.client.statusAction(async status => {
			const blobId = new Uint8Array(8);
			const blobHandle = await attachment.attachmentHandle!.createBlobAsync(
				status, transaction.transactionHandle, blobId, 0, undefined);

			const blob = new Blob(attachment, blobId);

			const blobStream = new BlobStreamImpl(blob, attachment);
			blobStream.blobHandle = blobHandle;
			return blobStream;
		});
