Need Help unable to delete cookie in Express

app.get("/logout", auth, async (req, res) => {  try {    req.user.tokens = req.user.tokens.filter((currentElement) => {    return currentElement.token !== req.token })    res.clearCookie("jwt");    console.log("Logout Successful");    await req.user.save();    res.render("/");  } catch (error) {    res.status(500).send(error);  }});

const auth = async (req, res, next) => {    try  {        const token = req.cookies.jwt;        const verifyUser = jwt.verify(token, process.env.SECRET_KEY);        console.log(verifyUser);        const user = Register.findOne({ _id :verifyUser._id});        console.log(user.firstname);        req.token = token;        req.user = user;        next();         } catch (error) {        res.status(401).send(error);    }}
