Turn off a duration (30 days) in date picker

Hello , i asked for help on this forum few days ago and i provided the code snippet i used trying to turn off certain dates in the date picker from 28-6-2023 to 30-7-2023 , i got a reply to report the problem from the dashboard of the plugin on my site ( i have the paid version) i could not find a place to report , i checked the snippets and used one but it did not work. the snippet will be provided below.

 
function wpf_limit_date_picker() {
    ?>
    <script type="text/javascript">
        var d = new Date();
        window.wpforms_datepicker = {
            disableMobile: false,
            // Don't allow users to pick specific range of dates
            disable: [
                {
                    from: "2023-6-28",
                    to: "2023-7-31"
                }
            ]
        }
    </script>
    <?php
}
add_action( 'wpforms_wp_footer_end', 'wpf_limit_date_picker', 8071 );
