Add a link to the product page woocomerce - wordpress

Question

I have made a custom field in the product card and displayed it in the catalogue, but the problem is that there is no link to go to the product card. I would appreciate any help.
Here is the code for adding a field in the product card
// Field Short name
add_action( 'woocommerce_product_options_general_product_data', 'shorttitle_custom_general_fields' );
add_action( 'woocommerce_process_product_meta', 'shorttitle_custom_general_fields_save' );
function shorttitle_custom_general_fields() {
global $woocommerce, $post;
echo '<div class="options_group">';
woocommerce_wp_text_input(
array(
'id' => 'shorttitle_field',
'label' => __( 'Краткое название', 'woocommerce' ),
//'desc_tip' => 'true',
//'description' => __( 'Краткое название', 'woocommerce' ),
'type' => 'html'
)
);
echo '</div>';
}
function shorttitle_custom_general_fields_save( $post_id ){
// Text Field
$woocommerce_text_field = $_POST['shorttitle_field'];
if( !empty( $woocommerce_text_field ) )
update_post_meta( $post_id, 'shorttitle_field', esc_attr( $woocommerce_text_field ) );
}
This is the code for displaying this field on the catalogue page
// Change the output of the product header (in the catalogue)
remove_action( 'woocommerce_shop_loop_item_title', 'woocommerce_template_loop_product_title' );
add_action( 'woocommerce_shop_loop_item_title', 'custom_woocommerce_template_loop_product_title', 99 );
function custom_woocommerce_template_loop_product_title() {
global $post;
$product = wc_get_product( $post->ID );
$title = get_post_meta( $post->ID, 'shorttitle_field', true );
if( $title ) {
echo '<h2 class="woocommerce-loop-product__title">' . esc_html( $title ) . '</h2>';
} else {
echo '<h2 class="woocommerce-loop-product__title">' . esc_html( $product->get_title() ) . '</h2>';
}
}
