Adding alt host for an established reoccurring meeting

Hello-

I scheduled a reoccurring meeting with a large number of people. After the first meeting, I realized that I had not added alt hosts that were needed. I would like to avoid creating a new meeting as the meeting link is widely distributed, and if possible avoid resending it out to the entire list serve (but know this may be unavoidable). I have gone into the meeting settings on both the web app and the desktop app between meetings and added the alt hosts and they show up in the settings, however the alt hosts are still unable to start the meeting.

How do I update the current reoccurring meeting with the alt hosts?

Thanks!
