The brief description of this technique: You have to give Zoom or Skype 100% control and dominion of a computer. No option. They demand it. That means you have to record the show somewhere else.
There are sneaky ways to do this, too. Put a third computer into the connection that has no microphone. Record the speaker feed (both voices, right?). We used to do that at work when we couldn’t figure out how to record production meetings and we had an extra computer.
In all of these techniques you have to add a computer or a recorder and you can’t mess with the Zoom machine.
Fair warning you might be able to fudge and mess around and get it to work on one machine, but it may only work until the next Zoom update.
