Our company is also looking to switch our trainings from Zoom webinar to Zoom meeting due to additional functionality such as break out rooms. We currently have Hubspot workflows built to add our training attendees to Zoom webinars automatically, and then manually approve the attendees in Zoom after we ensure they are qualified to attend.
With the lack of integration between Hubspot and Meetings, we would either have to ask our attendees to register a twice (once using a Hubspot landing page then a second time for the Zoom meeting), or we would have to change the Zoom registration to an open link and could then have people join that we do not want in the trainings which causes a security problem.
Either case can lead to a possible poor user experience. Please create the same functionality you already have with Zoom webinar for meetings aswell!
