如何在hyperledger fabric的nodesdk中根据我的组织名称添加自定义从属关系？

const { Gateway, Wallets } = require('fabric-network');
const fs = require('fs');
const path = require('path');

async function main() {
  try {
    // 创建一个新的网络连接对象
    const gateway = new Gateway();

    // 读取连接配置文件
    const connectionProfilePath = path.resolve(__dirname, 'connection.json');
    const connectionProfile = JSON.parse(fs.readFileSync(connectionProfilePath, 'utf8'));

    // 连接到Fabric网络
    await gateway.connect(connectionProfile, {
      walletPath: path.resolve(__dirname, 'wallet'),
      identity: 'user1',
      discovery: { enabled: true, asLocalhost: true },
    });

    // 获取通道对象
    const network = await gateway.getNetwork('mychannel');

    // 获取组织对象
    const org = network.getOrganization('Org1MSP');

    // 添加自定义从属关系
    org.addPeer('peer1.org1.example.com');

    // 添加排序节点
    org.addOrderer('orderer.example.com');

    // 初始化网络连接对象
    await gateway.initialize();

    // 获取最终的通道对象
    const channel = network.getChannel();

    // 执行你的业务逻辑...

    // 断开与Fabric网络的连接
    gateway.disconnect();
  } catch (error) {
    console.error(`Failed to submit transaction: ${error}`);
    process.exit(1);
  }
}

main();
