How to use the @liskhq/lisk-transactions.SecondSignatureTransaction function in @liskhq/lisk-transactions

secondSignatureAccountState.find(
		account => account.address === accounts.existingDelegate.address,
	).secondPublicKey =
		'62e4d09ce3fa571fb4b073fb229f5ff18b6108ca89357924db887a409f61542c';

	const targetAccount = secondSignatureAccountState.find(
		account => account.address === accounts.existingDelegate.address,
	);

	targetAccount.balance = parseInt(
		new BigNum(targetAccount.balance.toString()).sub(500000000).toString(),
		10,
	);

	const newSecondPassphraseTx = new SecondSignatureTransaction(
		secondPassphraseObject,
	);
	newSecondPassphraseTx.sign(accounts.existingDelegate.passphrase);

	const blockWithNewSecondSignatureNewRegistration = createBlock(
		defaultConfig,
		resultingAccountState,
		block,
		3,
		0,
		{
			version: 1,
			transactions: [newSecondPassphraseTx],
		},
	);

transferTx.sign(accounts.genesis.passphrase);

	const secondSignature =
		'erupt sponsor rude supreme vacant delay salute allow laundry swamp curve brain';
	const { publicKey } = getKeys(secondSignature);
	const secondPassphraseObject = {
		timestamp,
		senderPublicKey: accounts.existingDelegate.publicKey,
		asset: {
			signature: {
				publicKey,
			},
		},
	};

	const secondPassphraseTx = new SecondSignatureTransaction(
		secondPassphraseObject,
	);
	secondPassphraseTx.sign(accounts.existingDelegate.passphrase);

	const block = createBlock(
