Is your feature request related to a problem? Please describe.

As a Nextcloud user I want to schedule a meeting from an email thread quickly. I can open up a thread, open the actions menu of an email, click More actions and Create event to get an event creation modal. The title is filled with the email subject. There is no description.

Describe the solution you'd like

Use an LLM/Nextcloud assistant pick an event title and an event descrption.
