Docusign PHP SDK:如何通过sdk一次调用更新整个信封？

use DocuSign\eSign\Client\ApiClient;
use DocuSign\eSign\Configuration;

$config = new Configuration();
$config->setHost('https://demo.docusign.net/restapi');
$config->addDefaultHeader('Authorization', 'Bearer ' . $accessToken);

$apiClient = new ApiClient($config);

use DocuSign\eSign\Model\EnvelopeDefinition;
use DocuSign\eSign\Model\Recipients;
use DocuSign\eSign\Model\Signer;

$envelopeDefinition = new EnvelopeDefinition();
$envelopeDefinition->setEnvelopeId($envelopeId);

$recipients = new Recipients();
$signer = new Signer();
$signer->setEmail('recipient@example.com');
$signer->setName('Recipient Name');
$signer->setRecipientId('1');
$recipients->setSigners([$signer]);

$envelopeDefinition->setRecipients($recipients);

$envelopesApi = new DocuSign\eSign\Api\EnvelopesApi($apiClient);
$updateOptions = new DocuSign\eSign\Api\EnvelopesApi\UpdateOptions();

$result = $envelopesApi->update($accountId, $envelopeId, $envelopeDefinition, $updateOptions);
