Can I set optional in AttendeeList in calendar event in UiPath.GSuite.Activities.CreateEvent?

Hi everyone!!!
I’m new programmer on UiPath to try new function on GSuite.
I would like to know more about Calendar

on property variable “AttendeeList”.

My question is Can I set the person in AttendeeList to be optional in calendar event?

I have no idea How to do it.

Thank you.
