How does use:enhance customization work?

<form method="POST" use:enhance={({ formData, cancel }) => {
  submitting = true;
  return async ({ result, update }) => {
    submitting = false;
    await update();
  };
}}>

• ✓Correct answer: The outer function runs before submit (can cancel or modify data); the returned callback handles the result and update() applies the default behaviour
• 2It only accepts a URL
• 3Customization requires a separate library
