Jitsi Meet is not the same as Jitsi (Desktop). It's the open-source client that works with the equally open-source Jitsi server. Most features are identical to the web version which runs in any web browser, however, there's one big difference: If you want your computer to be remote-controlled, you have to use this client because the web version cannot acquire the necessary permissions to let the mouse and keyboard be controlled remotely through the web browser. This is a very useful feature e.g. for pair programming or in-house support.
