OAuth2 PHP change invalid_token response

Question

I'm using this library : Oauth2 PHP

Is there a way to modify the response when token is invalid or expired from codeigniter filter?

class OauthFilter implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        $oauth = new Oauth();
        $request = Request::createFromGlobals();
        $response = new Response();


        if(!$oauth->server->verifyResourceRequest($request)){
            $oauth->server->getResponse()->send();      
            die();
        
       }
    }

    public function after(RequestInterface $request, ResponseInterface $response, $arguments = null)
    {

    }
}

The default response was

{
    "error": "invalid_token",
    "error_description": "The access token provided is invalid"
}

I know that verifyResourceRequest also calls getAccessToken. When I tried it separately it returns null.

$oauth->server->getAccessTokenData($request,$response)
