Make Order notes field required only when it is not hidden in Woocommerce checkout

In Woocommerce checkout page, I have managed to show or hide "Order notes" field when "ship-to-different-address" checkbox is checked or unchecked, using "Show hide Order notes field based on a checkbox in Woocommerce checkout" answer code to one of my questions.

I would like "Order notes" field to be required only when it's visible.
How can I make this "Order notes" field required when it's visible (not hidden) and enable the validation for it?

Any help is welcome.

The following code will make "Order notes" field to be required only when it's not hidden and will enable in this case the field validation.

Note (mandatory): The "Order notes" field has to be optional (just as in default Woocommerce), without that the code will not work properly.

The complete code:

// Remove "(optional)" label on "Order notes" field
add_filter( 'woocommerce_form_field' , 'remove_order_comments_optional_fields_label', 10, 4 );
function remove_order_comments_optional_fields_label( $field, $key, $args, $value ) {
    // Only on checkout page for Order notes field
    if( 'order_comments' === $key && is_checkout() ) {
        $optional = '&nbsp;<span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) . ')</span>';
        $field = str_replace( $optional, '', $field );
    }
    return $field;
}

// The jQuery script that show hide "Order notes" field
add_action( 'woocommerce_after_order_notes', 'custom_checkout_scripts_js_script', 10, 1 );
function custom_checkout_scripts_js_script( $checkout ) {
    $required = esc_html__( 'required', 'woocommerce' );

    ?>
    <script type="text/javascript">
    (function($){
        var required     = '<abbr class="required" title="<?php echo $required; ?>">*</abbr>',
            notesField   = '#order_comments_field',
            shipCheckbox = '#ship-to-different-address-checkbox';

        function actionRequire( actionToDo='yes', selector='' ){
            if ( actionToDo == 'yes' ) {
                $(selector).addClass("validate-required");
                $(selector+' label').append(required);
            } else {
                $(selector).removeClass("validate-required");
                $(selector+' label > .required').remove();
            }
            $(selector).removeClass("woocommerce-validated");
            $(selector).removeClass("woocommerce-invalid woocommerce-invalid-required-field");
        }

        // On load and on form change
        $('form.checkout').on( 'change', shipCheckbox, function(){
            if( $(this).prop('checked') === true ) {
                $(notesField).hide(); // Show
                actionRequire( 'no' ,notesField );
            } else {
                $(notesField).show(); // Hide
                actionRequire( 'yes' ,notesField );
            }
        });
    })(jQuery);
    </script>
    <?php
}

// "Order notes" field validation
add_action('woocommerce_checkout_process', 'order_comments_field_validation');
function order_comments_field_validation() {
    if ( isset($_POST['order_comments']) && empty($_POST['ship_to_different_address']) )
        wc_add_notice( __( 'Please fill in "Order notes" required field.' ), 'error' );
}

Code goes on function.php file of your active child theme (or active theme). Tested and works.
