I have solved the issue just fix the following points.

1. Install correct plugins

   npm install --save @fullcalendar/timegrid @fullcalendar/interaction

2. Import in your appointment-Calendar.Component.ts file

   import timeGrid from '@fullcalendar/timegrid';

   import interaction from '@fullcalendar/interaction';

3. Update your calendarPlugins list with the following :

   calendarPlugins = [dayGridPlugin, timeGrid, interaction];
