I'm trying to make a dynaimc route.
I can access /user,/user/activities and /user/activities/1 However, on the last one I was expecting to be able to get the activityId in the params like this, however params doesn't contain anything like an activityId ?

import React from "react";
import { withPageAuthRequired } from "@auth0/nextjs-auth0";

export default function ActivityPage({ params }) {

    const activityId = params.activityId

    return (
        <div>
            <h1>Activiteis IndexPage</h1>
        </div>
    );
}
export const getServerSideProps = withPageAuthRequired();
