I’m following a course on Pluralsight that uses the Playground, but in the course there are parameters available for the playground to the right of the screen.
Can you post a screenshot of your Playground, so we can see what may be happening? In the Playground pane, just to the right of the word “Playground”, you need to ensure “Chat” is selected from the drop down (rather than “Assistants” in order to view parameter settings.
Sorry I was going to post a screenshot of my Playground but I was only allowed one screenshot and I thought the one from the training was the one to go with…
