title: Fullcalendar - add data to the bottom section of day cell (fc-daygrid-day-bg)
body: <p>This is the fullcalendar html structure:
  <a href="https://i.stack.imgur.com/sFnFF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/sFnFF.png" alt="enter image description here" /></a></p>
  <p>The fullcalendar cells are divided into 3 categories, and for the first 2 I was able to tap into and add custom data/styling:</p>
  <ul>
  <li><code>fc-daygrid-day-top</code> (modified using the <code>dayCellContent</code> from CalendarOptions)</li>
  <li><code>fc-daygrid-day-events</code> (modified using the <code>eventContent</code> from CalendarOptions)</li>
  <li><code>fc-daygrid-day-bg</code> ???</li>
  </ul>
  <p>Is there a way to tap into the third one as well(the highlighted line of code)?</p>
