Cannot Get Prop Of NextRequest

I'm trying to MiddleWare With Next.js's Middleware and JWT.

When I console.log cookies and typeof cookies variable im getting on console:

{
  token: 'token='myToken'; Path=/'
}

object

Here is my code:

import { NextRequest, NextResponse } from "next/server";
import { verify } from "jsonwebtoken";

const SECRET = process.env.SECRET;

export function middleware(req, res) {
  const cookies = req.cookies;
  
  const url = req.url;
  
  if (url.includes("/admin")) {
      console.log(cookies)
      console.log(typeof cookies)
    
  }

  return NextResponse.next();
}

But when i try to get token prop like cookies.token, i got undefined

Any idea of what's going on?
