Set access to user_register page

[RomainLWiz]

Hello, I wish I could put access to a group on the user_register page.
I found a solution :

{% if ((grav.user.authorize('site.csm')) and (uri.path == "/user_register")) or (uri.path == "/user_profile") %}
{% extends "forms/default/form.html.twig" %}
{% else %}
{% do grav.redirect('/user_register') %}
{% endif %}

The problem is that I am forced to redirect to a page that has real access. So after my connection I must write again the links. My goal is to remove this redirection or to redirect me directly to the right page after the connection.

Have a good day
