I get an alert every time I set up a meeting, because of new continuous meeting chat. How disable?

I hate this feature. I didn't ask for it and it gives me an alarm dialog every single time I set up  a meeting because some idiot at Zoom central decided to change how people's workflow works.

I want to disable it.

Have gone and looked. Cannot find these controls. I have a single user zoom account. what's all of this talk about signing into the web portal as an admin?  WTF?  So frustrated. https://support.zoom.us/hc/en-us/articles/115004809306-Enabling-or-disabling-in-meeting-chat#:~:text=In%20the%20navigation%20menu%2C%20click,to%20enable%20or%20disable%20it.
