Future<String> sendPayment({
  required Account account,
  required Address recipient,
  required BigInt amount,
  String? note,
  bool waitForConfirmation = false,
  int? timeout,
}) async {
  // Fetch the suggested transaction params
  final params = await getSuggestedTransactionParams();

  // Build the transaction
  final transaction = await (PaymentTransactionBuilder()
        ..sender = account.address
        ..noteText = note
        ..amount = amount
        ..receiver = recipient
        ..suggestedParams = params)
      .build();

  // Sign the transaction
  final signedTx = await transaction.sign(account);

  // Send the transaction
  return sendTransaction(
    signedTx,
    waitForConfirmation: waitForConfirmation,
    timeout: timeout ?? _options.timeout,
  );
