Zoom screen share no longer works with Wayland after August update

There was an update from Zoom in early August 2023 (I forget the exact date) that has broken screen share completely for me and partly for a colleague who also uses Linux. We both have Ubuntu 22.04 LTS machines, reimaged onto Dell machines that were originally windows. I won't write more details because after a search, I thought it might be due to Wayland, and it was. So I will add my answer here to help others find it.
