The following works perfectly fine: ```python calendar.birthdays.create_event( start_date_time="2025-05-05", end_date_time="2025-05-06", summary="Event#1", description="Lorem", location="Ipsum" ) ``` But this does not work ```python calendar.birthdays.create_event( start_date_time="2025-05-05", end_date_time="2025-05-06", summary="Event#1", description="Lorem", location="Ipsum", rrule="FREQ=YEARLY" ) ``` Leads to: `Exception in <jupyter_1> line 7: rrule="FREQ=YEARLY" ^ MultipleInvalid: extra keys not allowed @ data['rrule']` Though the calendar entity has such attributes in homeassistant according to the documentation here: https://developers.home-assistant.io/docs/core/entity/calendar/#calendarevent Can you please check? Many thanks!
