If a List has a People Custom Field established and a Create Google Calendar event integration automation set up, it would be efficient and useful for my organization if the Attendees field in the calendar event automation could be set to pull whatever user is in the People Custom Field and invite them to the calendar event.
Just inviting the Task's Watchers would not be efficient or effective for my organization because it would clutter calendar notifications for the admins and finance professionals who have been tagged in to work on the Task throughout its completion.
The users who need the calendar invitation are seldom the Assignees since those users' input and role in the hand-off happens prior to the Clickup task generation. I have considered building an automation to assign the task to the traveler right before the calendar event is generated, but I also do not want to clutter up PM's ClickUp notifications with a Task assignment that requires no action from them just so that someone does not have to manually go find the calendar invite and invite the Traveler.
