How to create a new genesis block

const { TokenModule, DPoSModule, KeysModule, SequenceModule, genesis, passphrase, cryptography, configDevnet } = require('lisk-sdk');

// Create the accountAssetSchemas

const keys = new KeysModule(configDevnet.genesisConfig).accountSchema;
const sequence = new SequenceModule(configDevnet.genesisConfig).accountSchema;

// Add fieldNumber starting from 2. Field number 1 is assigned to address of the account
token.fieldNumber = 2;

sequence.fieldNumber = 5;

// Creating the genesis account list

};

const credentials = [];


const newDelegate = (name) => {

  credentials.push(cred);
  const delegate = {
    address: Buffer.from(cred.binaryAddress, 'hex'),
    token: { balance: BigInt(100000000) },
