Zoom Outlook client Extension "Join Online" button not appearing

The Zoom extension Outlook client on Windows doesn't display the "Join Online" button on the reminder popup box nor in the Outlook calendar pane (optionally displayed on left in main mail window). I believe this is a feature that should work for Zoom when the extension is installed in Outlook and close to meeting start time.

I have the Join Online button for MS Teams in Outlook client just not for Zoom.

It does appear for Zoom in the Outlook on the Web version and iOS.

Is this still supported and supposed to work in Outlook client on Windows?

Thanks
