Calendar Event Window

I've started to experiment with more Mac-style windows. Here's my first attempt looking at a calendar event and it's details.

Areas for future consideration:
• Whether further investigation is needed for timezones and multi-day events,
• How additional attendees, including resource attendees, are handled,
• Whether an option to copy video call videos directly could work. Let's be honest, Zoom butchers an events description!
• Whether it could be cleverer in how it displays location and meeting details depending on the event provider.

All feedback appreciated :) Crisp original attached.
