“client” is a custom post type because I have to add several metaboxes.
For a better ergonomy on admin side, I would like to add my custom post type “client” as “users” submenu.

I understand to display a custom post type, normally urls are :

1. https://my-site.com/wp-admin/edit.php?post_type=client
2. https://my-site.com/wp-admin/post-new.php?post_type=client

When I add “client” inside users menu, I got this url :

https://my-site.com/wp-admin/users.php?page=client

So, that does not work.

How can I get the client edition with list/post-new/edit-new based on the last url ?
