How to use the @electron-forge/core.api.package function in @electron-forge/core

.arguments('[cwd]')
    .option('-a, --arch [arch]', 'Target architecture')
    .option('-p, --platform [platform]', 'Target build platform')
    .action((cwd) => { dir = workingDir(dir, cwd); })
    .parse(process.argv);

  initializeProxy();

  const packageOpts: PackageOptions = {
    dir,
    interactive: true,
  };
  if (program.arch) packageOpts.arch = program.arch;
  if (program.platform) packageOpts.platform = program.platform;

  await api.package(packageOpts);
})();
