Yes. The join via web button should join after you click the regular "join" link once. If you don't have zoom installed it will just pop up not working then you can join via web.

I also use https://addons.mozilla.org/en-CA/firefox/addon/zoom-redirect... to fix up the URL automatically.

It's been a little while since then, but I remember downloading at least three executables, getting annoyed, And setting up a google meet event instead.

It is possible, but it misses features. For example, the thing that I ran into recently is that web zoom cannot switch between multiple camera's of another person on the call -- e.g. if they have some fancy conference room setup.
