Is it possible to accept/reject without sending response?

Hi,

First of all I would like to thank you for creating this add-on, which
makes my life easier on Linux desktop.

I am not sure if my company exchange server has special configuration
that is different with normal ones. Every time I accept a event which
sent to a group, my response would be send to the group. This is
sometimes not I want since the group contains a large number of
employees. The problem is if I don't accept, the event wouldn't show up
in calendar. In Microsoft outlook it has a options says accept without
sending response.

Not sure if there is any other workaround. Looking forward to hear from you.

Thanks again!
