Extend Meeting on Zoom One Basic Plus

I was going to cancel  Zoom Pro today because I was feeling like the price of the Pro plan was too high for my infrequent use and not needing many of the features. When I clicked in to cancel, Zoom offered an option to go to a new Beta tier called Zoom One Basic Plus that's more like Basic but allows for extending up to 4 meetings/month to 80 minutes, so I decided to give that a try, but now I don't know how to use the meeting extensions and haven't been able to find any information about it in the support area so far. I realize I may be looking in the wrong place. Does anyone know more about this & could help me figure out how to use this new feature?
