I would like to track how users progresses with my quizzes. So, I should track somehow the following information:quiz idquestion idanswer user gaveAlso, I should track additional information (like user started the quiz, user returned back to the previous question etc.).I am thinking about events usage, but can not understand what to assign to category, action, label and value. The category could be answer, the value is the actual answer user gave, but where to pass quiz id and question id?
