How to invite zoom attendees on an iMac

👍I have an iMac using the latest upgrade Sequoia 15.3.1. 

👍When I generate A Zoom meeting I can save it in my Calendar using the link in 'My Meetings' by using 'Outlook Calendar' (.ics) 

👎I cannot then seem to send anyone else an invite - even if i put them in the original invite generated when I am setting up the meeting OR to invite them from the calendar itself - any advise really welcome
