How to use the @foal/typeorm/node_modules/typeorm.getManager function in @foal/typeorm

const user = new User();
  user.email = 'john@foalts.org';
  await user.setPassword('password');

  const user2 = new User();
  user2.email = 'mary@foalts.org';
  await user2.setPassword('password2');

  const permission = new Permission();
  permission.name = 'Admin permission';
  permission.codeName = 'admin';

  user.userPermissions = [ permission ];

  console.log(
    await getManager().save([ permission, user, user2 ])
  );
}
