Read more button in wordpress

Question

I have this snippet to make a read more button for content in a single product. it works well.

But I want the read button will disappear when the content is under the limit that I set (34 words).

What should I add to this code to make the button disappear if the word counts less then 34?

// Shorten product long description with read more button
function filter_the_content( $content ) {
// Only for single product pages
if( ! is_product() ) return $content;

// Set the limit of words
$limit = 34;

// Strip p tags if needed
$content = str_replace( array( '<p>', '</p>' ), '', $content );

// If the content is longer than the predetermined limit
if ( str_word_count( $content, 0 ) > $limit ) {
    // Returns an associative array, where the key is the numeric position of the word inside the string and the value is the actual word itself
    $arr = str_word_count( $content, 2 );
    
    // Return all the keys or a subset of the keys of an array
    $pos = array_keys( $arr );
    
    // First part
    $text = '<p>' . substr( $content, 0, $pos[$limit] ) . '<span id="dots">...</span>';
    
    // More part
    $text .= '<span id="more">' . substr( $content, $pos[$limit] ) . '</span></p>';
    
    // Read button
    $text .= '<button id="read-button"></button>';
    
    $content = force_balance_tags( $text ); // needded
}
?>
<script type="text/javascript">
    jQuery(document).ready( function ($) {
        // Settings
        var read_more_btn_txt = 'Read more';
        var read_less_btn_txt = 'Read less';
        
        // Selectors
        var more = '#more';
        var read_button = '#read-button';
        var dots = '#dots';
        
        // On load
        $( more ).hide();
        $( read_button ).html( read_more_btn_txt );

        // On click
        $( read_button ).on( 'click', function() {
            if ( $( more ).is( ':hidden' ) ) {
                $( more ).show();
                $( dots ).hide();
                $( read_button ).html( read_less_btn_txt );
            } else {
                $( more ).hide();
                $( dots ).show();
                $( read_button ).html( read_more_btn_txt );
            }
        });

    });
</script>
<?php
    return $content;
}
add_filter( 'the_content', 'filter_the_content', 10, 1 );
