Will a co-organizer be able to modify / edit a meeting text and/or datetime?

This is coming soon according to Microsoft Message Center post MC688109. It's associated with Microsoft 365 Roadmap ID https://www.microsoft.com/en-us/microsoft-365/roadmap?filters=&searchterms=168524

The message center post says: "So far co-organizers were able to set up event theming, manage registration, meeting options, view reports and more but were not able to edit event details like title, date/time, description, event group; nor publish or cancel event. Now they can! Co-organizer can edit event details, publish, and cancel the event like the organizer can. So once the co-organizer is added they will have full parity of experience as organizer and control/manage/edit event."

When this will happen:

Targeted release: We will begin rolling out early June 2024 (previously mid-April) and expect to complete by mid-June 2024 (previously late April).

General Availability: We will begin rolling out mid-June 2024 (previously late April) and expect to complete by early July 2024 (previously early May).
