Gesture Recognition not Working on iMac

Have already started a chat with support but trying to figure out why gesture recognition isn't available in my Zoom settings on my iMAC [Mac (21.5-inch, Late 2012) running Mojave 10.14.6]. The same Zoom account is used on a MacBook Air and it has the option available. See the screenshots.

I haven't seen anything in the release notes that says the feature isn't available on certain machines or operating systems. Both computers have the latest Zoom desktop app.

Anyone else having this issue?
