is_paged returning fales incorrectly | WordPress Comments

I have modified the comments.php file of the theme, but I’m told the is_paged is returning false when the comments are actually paginated.

Here is the code:

<?php
/**
 * The template for displaying comments.
 *
 * This is the template that displays the area of the page that contains both the current comments
 * and the comment form.
 *
 * @package HelloElementor
 */

if (!defined('ABSPATH')) {
    exit; // Exit if accessed directly.
}

if (!post_type_supports(get_post_type(), 'comments')) {
    return;
}

if (!have_comments() && !comments_open()) {
    return;
}

// Comment Reply Script.
if (comments_open() && get_option('thread_comments')) {
    wp_enqueue_script('comment-reply');
}

// Check if we're on a paginated comments page
$is_comments_paged = (get_query_var('cpage') > 1);

?>
<section id="comments" class="comments-area">
    <?php
    comment_form(
        [
            'id_form'       => 'commentform',
            'comment_field' => '<p class="comment-form-comment"><label for="comment">' . __('Join the discussion', 'text-domain') . '</label><textarea id="comment" name="comment" cols="45" rows="5" style="height: 100px;" placeholder="' . __('Type Here...', 'text-domain') . '" aria-required="true"></textarea></p>',
            'fields'        => [
                'author' => '<p class="comment-form-author"><label for="author">' . __('Display Name', 'text-domain') . '</label> ' .
                    ($req ? '<span class="required">*</span>' : '') .
                    '<input id="author" name="author" type="text" value="' . esc_attr($commenter['comment_author']) . '" size="30" placeholder="' . __('Display Name', 'text-domain') . '"' . $aria_req . ' /></p>',
                'email'  => '<p class="comment-form-email"><label for="email">' . __('Email Address (Not Shown Publicly)', 'text-domain') . '</label> ' .

            <?php
            $comments_number = get_comments_number();
            if ('1' === $comments_number) {
                printf(esc_html_x('One Comment', 'comments title', 'hello-elementor'));
            } else {

Any thoughts?

I saw another post on here where the solution was that a condition wasn’t closed. But, I do not see that as a problem here.

I tried setting the is_paged in this comments.php, but I couldn’t get anything to work.

I checked with ChatGPT code interpreter.

I took out the no follow code part.

When fixed, RankMath should automatically change the pagnated pages to noindex. I know this is something I can do editing the funtions.php file, but I’d like it to work properly instead.
