Update recurring lecture
This API endpoint allows you to update a recurring lecture by specifying a recurrence rule. The recurrence rule must follow the [iCalendar specification](https://icalendar.org), using the `DTSTART` and `RRULE` elements to define the lecture's start date and recurrence pattern.
#### Parameters
- rrule: A string defining the start date and recurrence rule, following the iCalendar format. The rule consists of:
- A `DTSTART` element on the first line, specifying the start date and time of the lecture.
- An `RRULE` element on the second line, specifying the recurrence pattern (e.g. daily, weekly, monthly).
Each element must be on its own line, separated by a newline character (`\n`). Give both times in UTC (a trailing `Z`), for example:
```
DTSTART:20260907T090000Z
RRULE:FREQ=WEEKLY;BYDAY=MO,WE;UNTIL=20261218T235959Z
```
