title: How to use FullCalendar resourceTimeGridDay in v 4.3.1?
body: <p>I'm using <code>resourcetimegrid</code> plugin, but it only works when I use <code>defaultView:'resourceDayGridDay'</code> and for sure it only shows the day without showing the hours, but I want to use <code>resourceTimeGridDay</code> to be able to see the hours.</p>
  <p>This code works for <code>resourceDayGridDay</code>, but the hours don't show up.</p>
