I have received an update from Google and they have provided us another way to manage Nicknamed Meets. This method is my recommendation for ease of use and for security purposes.
You can now create shortcode URLs and students will have access.
URL Format: meet.google.com/lookup/nickname
So, if you create this link, just make sure you go to it first to claim it. I have created a video tutorial below to explain the Google Meet Shortcode complete with an example meeting.
