Add To calendar button plugin is not working

I have installed the 'Add to calendar button' plugin for my site, i have just installed and have not made any settings or any of such kind, there was only one option visible under 'Add to calendar' menu in my wordpress that is 'Load script unstyled'. And later to display the calendar in my site i have used a shortcode, which i got from your documentation site. The code i have used is 

     <add-to-calendar-button

  name="[Reminder] Test the Add to Calendar Button"

  startDate="2024-03-29"

  startTime="10:15"

  endTime="23:30"
