[Solved] Link from username to commentsection in profile

Hello friends

I played around with the redirection to the profile if you click on a username.

The link to the user commentsecction is:

https://www.blueaustria.at/members/blueaustria/comments/

where "blueaustria" is the loginname.

I tried the following code, but it doesnt work for me, i hope you can help me =)

//WP Discusz Profile Redirection
add_filter("wpdiscuz_profile_url", function ($profile_url, $user) {
    if ($user->display_name) {
        $profile_url = site_url() . "/members/" . $user->display_name . "/comments/";
    }
   return $profile_url;
}, 10, 2);
