How to install and use RRule for Fullcalendar in Angular?

问题

fullcalenar does not have much documentation for Angular.

Installing the rrulePlugin does not work as I asked in the previous question :

Angular 9: Cannot find namespace 'FullCalendarVDom'?

this solution does not work either:

import { RRule } from 'rrule';

renderEvents(obj) {
   const rrule = new RRule({
        freq: RRule.WEEKLY,
        interval: 1,
        byweekday: [RRule.FR],
        dtstart: obj.dtstart as Date,
        until: obj.until as Date
    });

  events = {
    title: ...
    rrule: rrule
  }
}

as the events are rendered only once and the rrule object is ignored.

What is the solution? Is it even possible to use rrule in Angular?
