Uninstall extra Zoom Meeting application?
From the output of grep -R Zoom /usr/share/applications ~/.local/share/applications, it seems the duplicate Zoom is being provided by Chrome as a Chrome app.
To remove that, open Google Chrome and go to chrome://apps, right click and click on "Remove from Chrome".
Restart the GNOME shell if the icon still appears using:
- Alt+F2
- type
r - hit Enter.
