Add an Online Meeting for Bookings already booked

Hello!

Is there a way to add an Online Meeting for a booking services already published (option "Add Online Meeting" was unticked by mistake)?

There are already a lot of bookings that came in, so we can't cancel the service and re-issue a new bookings form.

TLDR - need the bookings already booked to have an option to Join the meeting instead of just a calendar booking without Join button.

Thanks I!
