How to use the @aws-crypto/material-management-node.KeyringTraceFlag.WRAPPING_KEY_ENCRYPTED_DATA_KEY function in @aws-crypto/material-management-node

const _wrapKey = async (material: NodeEncryptionMaterial) => {
      /* Precondition: Public key must be defined to support encrypt. */
      if (!publicKey) throw new Error('No public key defined in constructor.  Encrypt disabled.')
      const { buffer, byteOffset, byteLength } = unwrapDataKey(material.getUnencryptedDataKey())
      const encryptedDataKey = publicEncrypt(
        { key: publicKey, padding },
        Buffer.from(buffer, byteOffset, byteLength))
      const providerInfo = this.keyName
      const providerId = this.keyNamespace
      const flag = KeyringTraceFlag.WRAPPING_KEY_ENCRYPTED_DATA_KEY
      const edk = new EncryptedDataKey({ encryptedDataKey, providerInfo, providerId })
      return material.addEncryptedDataKey(edk, flag)
    }
