In my experience, that link only appears after you actively deny the opening of an external application (xdg-open alerts pop up), after 3 tries it will _finally_ appear. Quite infuriating.

Have you tried disabling Javascript? The "Join from your browser" URL follows a predictable format, only a slight variation from the meeting link. If you have a meeting link that someone sent you, you can create the web client URL yourself.

True. But there is an option to show it by default. Though it is not easy to find. And only the manager of the host account can do it.
