I am trying to link the comment author name to site url/profile/author username

I'm setting up a wordpress website where users can comment based on user roles. I would like to link the name of the comment author to their personal profile page (site url/profile/username).

I have almost 0 knowledge about PHP, and I know a bit of CSS. I have tried a couple of different code snippets in my child theme function.php, but none of them seem to work properly. The following snippet for example, only links the comment author name to site url/profile/user ID, but I would like it to be site url/profile/username

function force_comment_author_url($comment)
{
    // does the comment have a valid author URL?
    $no_url = !$comment->comment_author_url || $comment->comment_author_url == 'http://';

    if ($comment->user_id && $no_url) {
        // comment was written by a registered user but with no author URL
        $comment->comment_author_url = 'http://www.founderslair.com/profile/' . $comment->user_id;
    }
    return $comment;
}
add_filter('get_comment', 'force_comment_author_url');

I expect to get the username and not the user ID. I've tried some changes in the snippet but nothing seems to work. I'd like to know what I am doing wrong and what I can do to improve it. Thanks in advance.

You can make use of the inbuilt get_userdata function to find out the comment author username. I have explained the added coded in comments as suffix.

function force_comment_author_url($comment)
{
    // does the comment have a valid author URL?
    $no_url = !$comment->comment_author_url || $comment->comment_author_url == 'http://';

    if ($comment->user_id && $no_url) {
        
        $c_userdata = get_userdata( $comment->user_id ); // Add - Get the userdata from the get_userdata() function and store in the variable c_userdata
        $c_username = $c_userdata->user_login; // Add - Get the name from the $c_userdata

        // comment was written by a registered user but with no author URL
        $comment->comment_author_url = 'http://www.founderslair.com/profile/' . $c_username; // Replace - user_id with username variable.
    }
    return $comment;
}
add_filter('get_comment', 'force_comment_author_url');
