Identifying invitees after scheduling meeting

Welcome to the Zoom Community, @gbrant 

Zoom doesn't directly invite people to meetings, though there are several Zoom-provided add-ons that do so, but these use interfaces to Google Mail, Outlook, or other software.  For full information, see the articles in this Zoom Support collection:

To see who has been invited, you'd have to look at Outlook, Google, or other integrated systems.  Zoom doesn't maintain that information in the Zoom data cloud.
