To have an optimal Zoom experience, it's best to have the App.

You can access some of Zoom features through the App.

You need to access the Web Portal for a full list of options.

There are some features that can only be accessed through the Web Portal, such as reports, adding exception guests and creating permanent breakout groups, etc...

Keep in mind, there are some settings that if you change them in the desktop app, you're making the changes only on that particular device because it's local.

If you switch to another device, you will need to reapply the changes again to your new device.
