How can I use the Required Registration feature in this situation?

[Rosiezilinskas]

Set up: I currently have Zoom Workplace Pro
Current status: I have an existing invite for recurring weekly meetings for my membership with members already added to the meeting. 

What I'm trying to do:  I want to edit that existing weekly meeting to add a registration link for potential new members to join one time for free.  I can edit the current recurring series to make it required to register. 

But I don't want my existing members to have to register.  Since they already have the invite on their calendars with the zoom link to join the meeting, they will not have to register for the event each week.  Is that correct?  I want to provide the registration link to new people so that they receive the email and are able to add the session to their calendars.  

Is my thought process correct?  Please advise.  Thanks
