Hi sassran - I was searching recently for options to add a Google Meet video link to Apple Calendar appointments.
Unfortunately, there doesn't seem to be a way to do so. Neither Google nor Apple provide a way to create the Google Meet link, and I couldn't find any Calendar plug-in or third-party utility filling that gap.
I finally installed Microsoft Outlook on my Mac, and the Google Meet add-on for Outlook. This way, I can add a Google Meet link to meeting requests. This means you need to ditch Apple Calendar in favor of Outlook, though.
I hope this helps.
