Automating the Store notice

I want to automate the store notice and I think I have the code ready to do so. I just can’t figure out where I would implement it so that it would affect the store notice.

This is the code that I made for the store notice

Scheduled HTML Execution

<script>
    var days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
    var currentdate = new Date();
    var day = currentdate.getDay();
    var hour = currentdate.getHours();

    // Check if it's Friday and the time is 9 AM
    if (day === 5 && hour === 9) {
        // Run HTML code at the designated time
        var scheduledHtml = '<p class="woocommerce-store-notice demo_store" data-notice-id="63021a62384d5cd6d6cf42454d641e5a" style="display:block;" title="Shift-click to edit this element."><span class="customize-partial-edit-shortcut customize-partial-edit-shortcut-woocommerce_demo_store_notice"><button aria-label="Click to edit this element." title="Click to edit this element." class="customize-partial-edit-shortcut-button"><svg xmlns="https://www.w3.org/2000/svg" viewBox="0 0 20 20"><path d="M13.89 3.39l2.71 2.72c.46.46.42 1.24.03 1.64l-8.01 8.02-5.56 1.16 1.16-5.58s7.6-7.63 7.99-8.03c.39-.39 1.22-.39 1.68.07zm-2.73 2.79l-5.59 5.61 1.11 1.11 5.54-5.65zm-2.97 8.23l5.58-5.6-1.07-1.08-5.59 5.6z"></path></svg></button></span>"The St. Isidore Market is currently closed for online ordering.

        document.getElementById('scheduledContent').innerHTML = scheduledHtml;
    } else if (day === 2 && hour === 12) {
        // Remove the notice on Tuesday at noon
        document.getElementById('scheduledContent').innerHTML = "";
    } else {
        // Display the current date and time
        var ampm = hour >= 12 ? 'PM' : 'AM';
        hour = hour % 12;
        hour = hour ? hour : 12; // Handle midnight
        var datetime = "Current Time: " + days[currentdate.getDay()] + " " + currentdate.getDate() + "/"
                        + (currentdate.getMonth() + 1) + "/"
                        + currentdate.getFullYear() + " @ "
                        + hour + ":"
                        + currentdate.getMinutes() + ":"
                        + currentdate.getSeconds() + " " + ampm;

        document.getElementById('scheduledContent').innerHTML = "<p>" + datetime + "</p>";
    }
</script>
