Display Post co-authored in Author Page

I am using co-author plus and I have posts in my site that are done by multiple authors. I would like that when I click on the co-author’s author page, I will be able to get the posts that he/she co-authored.

For now, I am using a vanilla WP_Query call to primary authors. I followed db trail and the co-authors are posted on the wp_term_taxonomy table, but I am unsure on how to query and get that data.

Here is my paramters:

$arg = array(
        'author'        => strval($user_id),
        'post_per_page' => 10,
        'post_status'   => 'publish',
        'paged'         => strval($page)
    );

Use the Co-Authors Plus to assign the authors and the post will show automatically on both author pages. I’ve used it and works pretty well.
