example
const transactionManager = TransactionManager.fromWallet(wallet);
example
const keyStore = new keyStores.UnencryptedFileSystemKeyStore(credentialsPath);
const transactionManager = new TransactionManager({
 transactionCreator: new KeyStoreTransactionCreator({
   keyStore,
   signerId: wallet.getAccountId(),
   networkId: "testnet",
   nodeUrl: "https://rpc.testnet.near.org",
 }),
 transactionSigner: new KeyStoreTransactionSigner({
   keyStore,
   signerId: wallet.getAccountId(),
   networkId: "testnet",
 }),
