How to use the @twilio-labs/serverless-api.fsHelpers.getFirstMatchingDirectory function in @twilio-labs/serverless-api

export async function doesAnyDirectoryExist(
  basePath: string,
  directories: string[]
): Promise {
  let foundDirectories: string | undefined;
  try {
    foundDirectories = fsHelpers.getFirstMatchingDirectory(
      basePath,
      directories
    );
  } catch {
    foundDirectories = undefined;
  }

  if (typeof foundDirectories !== 'undefined') {
    return true;
  }

  return false;
}

export async function writeFiles(
  files: TemplateFileInfo[],
  targetDir: string,
  namespace: string
): Promise {
  const functionsDir = fsHelpers.getFirstMatchingDirectory(targetDir, [
    'functions',
    'src',
  ]);
  const assetsDir = fsHelpers.getFirstMatchingDirectory(targetDir, [
    'assets',
    'static',
  ]);
  const functionsTargetDir = path.join(functionsDir, namespace);
  const assetsTargetDir = path.join(assetsDir, namespace);

      } catch (err) {
        debug(err);
