Zoom Room Calendar Integration not working.

Hi. My account has a Zoom Roon feature and we've been using it for months now. We realized that it has no scheduled meeting as to what the original Zoom meeting can do. So calendar integration is one way of fixing the problem, so you can set a time and date on your calendar and assign it to your available Zoom Room. But my problem is that, when I follow the link : https://support.zoom.us/hc/en-us/articles/201474605-Scheduling-in-Zoom-Rooms-with-Google.

and watched tutorials on how to schedule in Zoom Rooms, I don't see the "Rooms" option beside the guest invitation section. (see first image)

But it should look this: (see second pic)

Any thoughts on how to make that option appear on my end?  Tried clearing my cache and cookies but to no avail.
