Calendar quiz has a question:
"
2. Where can I set a calendar event to be a recurrent event?
"
Possible answers are
Calendar > Attendees > Recurring
According to the quiz, correct answer would be A. However, in Odoo 18 none of the answers is correct. The "Recurrent" option is available directly in the main screen of the meeting. There are no separate "Options" or "Meeting details". In Odoo 16 the recurring information is under "Options" tab, but the whole tab has been combined to the same model in Odoo 18 (and probably 17).
