Userfront.js Middleware Express JsonWebTokenError: invalid signature

I am using userfront.js that will create a token on their side of things. https://userfront.com/test/dashboard/jwt/usage

to verify the token I am using the token creatred from userfront.js and public key from my user front account.

keep getting this error though: JsonWebTokenError: invalid signature

here is my code.

Middlware.js

var jwt = require("jsonwebtoken")

const key = Buffer.from(process.env.PUBLIC_KEY_64, "base64").toString("ascii")

const isAdmin = async (req, res, next) => {
   
   
   
  try {
    const token = req.cookies["access.pn4qd8qb"]

    const payload = jwt.verify(token, key, { algorithm: "RS256" })

    console.log({ payload })

    next()
  } catch (error) {
    console.log(error)
  }
}

module.exports = { isAdmin }

Note: not the full key not sure if I should post full key online
