list_tickets. And writing a test for it shows that in fact, it does. I know that in GraphQL, the successful response JSON will include a key list_tickets that contains the array of tickets. Ok so far, but it would be helpful to see an example of the GraphQL query, so that I can be confident, and not assume.list_tickets query to take a few query parameters? Where in the documentation does it give me information to make that happen? Looking at the example above again, what does the :read argument mean? I see above it in the example, there is another query, read_one :most_important_ticket, :most_important, and the second argument is :most_important. What does this mean?
