Just looked at episode 206... that will do me well. I suppose if I need a gem, for concerns etc, I can make it so you include the bits needed to get the javascript. Do something like add the appropriate lines to the /app/javascript/packs/application.js file etc.
I've resisted going to Turbo so far (not that I see it as bad but development timescales to convert projects etc) but it really seems to many situations easily now. Now to choose the first project...
