8 – Custom Authorization Not Appearing in / admin / people / permissions

I have a custom module my_module for Drupal 8 and I've added a custom permission yml file with 1 static permission:

modules / my_module / my_module.permissions.yml

My custom function permission:
title: Accéder Access the custom feature & # 39;
description: & nbsp; Gives access to custom functionality. & # 39;
restrict access: true

modules / my_module / my_module.info.yml

name: 'My custom module & # 39;
type: module
description: & # 39; Blah & # 39;
Core: 8.x
package: 'My company & # 39;

I was waiting to see a new authorization appear in mysite.com/admin/people/permissions under the category "My Business", but there is none.

Do I have to do anything else to get permission to view in / admin / people / permissions?

I followed these instructions:
