I'm trying to create and fetch quizzes in router using NodeJs, but it keeps fetching me quizzes of every user and not only the user that is logged in

const prefix = "/:userId/quizzes";

router.get(`${prefix}/my-quizzes`, userAuth, async (req, res) => {
  try {
    const quizes = await Quiz.find().populate({
      path: "category",
      select: ["name"],
    });

    res.send(quizes);
  } catch (error) {
    return res.status(404).json({
      message: "Can't fetch quizes !",
      success: false,
    });
  }
});
