attendees email addresses in invitation - hidden by default?

[szymon.augustyniak]

Dear All,

just wanted to make sure: 

are the attendee's email addresses hidden in Webex Meeting invitation (= people invited via WM cannot see each other addresses)?

is it a permanent opt-out? 

Thank you in advance, Sz

In all invitations I have seen, the other attendees' addresses were not mentioned in any way, which sounds logical, especially taking into account that it is possible to have Webex meeting attendees who do not provide _any_ e-mail address.
