How to do checkout on WooCommerce cart page?

Question

WordPress

Woocommerce has a notices folder where notifications are divided into files. error, success and notice.

So, I want to show a certain notification on certain pages, and the standard one on the rest.

For example, when returning a successful result, show some text on the cart page, and standard text on others.
I wrote the following code in success.php with a check: (but it doesn't work)

<?php
/**
 * Show messages
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/notices/success.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce/Templates
 * @version 3.9.0
 */

if ( ! defined( 'ABSPATH' ) ) {
  exit;
}

if ( ! $notices ) {
  return;
}

?>

<?php if(is_cart()) { ?>

  <?php echo esc_html__('Тут текст, например', 'skazkaMini') ?>

<?php } else { ?>

  <?php foreach ( $notices as $notice ) : ?>
    <div class="woocommerce-message test"<?php echo wc_get_notice_data_attr( $notice ); ?> role="alert">
      <?php echo wc_kses_notice( $notice['notice'] ); ?>
    </div>
  <?php endforeach; ?>

<?php } ?>
