How to return a response from a pre config? (HapiJS)

I have the path:

{
    method: 'GET',
    path: '/filesystem',
    config: {pre:[validateJWT]},
    handler: readDir
}

And two functions, the pre:

const validateJWT = async (req, res) => {
     . . .
    //returns true or false
}

And the handler:

const readDir = async(req, res) => {
  return res.response('Handler response').code(200);
};

How can I link the return value of the validateJWT function to use it in the readDir handler function?. Each function and the route are in different files.

Thanks.

To use the validateJWT function, you must assign a name to the function like this:

const validateJWT = () {
  return {
      method: async (req, _res) => {
        . . .
        //returns true or false
      },
      assign: 'validateJWT',
    };
}

And after doing this to retrieve the value of the function in readDir:

const readDir = async(req, res) => {
  // const {validateJWT} = req.pre;
  return res.response('Handler response').code(200);
};
