Are There Any Benefits To Using The Extension Over The Desktop App?

The main benefit of using the browser extension is that it is more convenient. Since you do not need to install programs if you use the extension, you can join or start meetings with a single click. The extension will then do all the work for your video conference session. Conversely, the desktop application requires you to go through some steps for the same action.
