Notify Registrants of Webinar Cancellation in a Series

[afoley]

We are cancelling a session of a webinar series. I only see an option to delete the date from occurrences, but this doesn't seem to notify the people who are already registered for the series about the cancellation. Is there a way in Zoom to do this? 

We are happy to send a separate email, I just want to make sure I'm not missing something.
