Is your feature request related to a problem? Please describe.
In talk rooms before a call takes place it is regularly discussed if the talk will happen or not. If it is decided the talk will not happen, I have to switch apps to the Calendar app to remove the agenda item.

Describe the solution you'd like
Be able to remove the calendar event from the talk room interface.

Describe alternatives you've considered
an AI automation that automatically recognizes that 80% of the team is sick / on vacation / has conflicting meetings and already proposes in the room to cancel the meeting and after thumbs ups cancels it for you

Additional context
/

Start by locating the Talk room interface and the existing integration with calendar events. Trace how an agenda item is represented and how the Calendar app removes it. Done means a user can remove the calendar event directly from the talk room without switching apps.
