I don't see the customize waiting room option.

The Waiting Room is disabled by default for instant meetings and Zoom Phone calls elevated to a meeting. You can only enable Waiting Room for these meetings using the Security option in your in-meeting controls

But in this article it is written that we can enable and customize the waiting room through the zoom web portal.

I have the same issue. I have enabled it in security, but there is no meeting room option or customisation below. It is not showing up at all. I have the free account, have they blocked customisation for this account level?
