Exited a future meeting for all...how to ensure that meeting can actual allow people to attend?

as the Host, I opened a future meeting in a series to get the URL. I clicked "End Meeting for All" vs. Leave. That meeting no longer has the "Start" button. The attendees for the meeting are from all over (a published meeting) so I have no way to inform them of a new meeting log in. How can I reinstate that meeting so I and everyone else can join? (meeting is on 3/16/23)
