// deleteContentCache shows how to delete content cache.
func deleteContentCache(w io.Writer, cacheName string) error {
	ctx := context.Background()

	client, err := genai.NewClient(ctx, &genai.ClientConfig{
		HTTPOptions: genai.HTTPOptions{APIVersion: "v1"},

	if err != nil {
		return fmt.Errorf("failed to create genai client: %w", err)
	}

	_, err = client.Caches.Delete(ctx, cacheName, &genai.DeleteCachedContentConfig{})
	if err != nil {
		return fmt.Errorf("failed to delete content cache: %w", err)
	}

	fmt.Fprintf(w, "Deleted cache %q\n", cacheName)

	// Example response:

    // once, and can be reused for multiple requests.
