the WSSecurityCert option no work

• The options WSSecurityCertm, when past the param options the class not use it

  the prefix not change
  const cerft = new soap.WSSecurityCert(certpri, ca, 'kpseos123', {
     prefix: 'ds',
   });

Additional information

i checked the core class, the class never user that param

class WSSecurityCert extends Security {
  constructor(privatePEM, publicP12PEM, password) {
    super();
    this.publicP12PEM = publicP12PEM.toString().replace('-----BEGIN CERTIFICATE-----', '').replace('-----END CERTIFICATE-----', '').replace(/(\r\n|\n|\r)/gm, '');
    this.signer = new SignedXml();
    this.signer.signingKey = this.getSigningKey(privatePEM, password);
    this.x509Id = 'x509-' + generateId();
    var references = ['http://www.w3.org/2000/09/xmldsig#enveloped-signature', 'http://www.w3.org/2001/10/xml-exc-c14n#'];
    this.signer.addReference('//*[local-name(.)=\'Body\']', references);
    this.signer.addReference('//*[local-name(.)=\'Timestamp\']', references);
    var _this = this;
    this.signer.keyInfoProvider = {};
    this.signer.keyInfoProvider.getKeyInfo = function (key) {
      var x509Id = _this.x509Id;
      var xml = `<wsse:SecurityTokenReference>
    <wsse:Reference URI="${x509Id}" ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3"/>
    </wsse:SecurityTokenReference>`;
      return xml;
    };
  }
```

Start at the WSSecurityCert constructor and its keyInfoProvider, especially the generated SecurityTokenReference XML. Trace how constructor options are passed and determine what it means for the configured prefix to be honored; done means the WSSecurityCert option affects the generated security XML as intended.
