Drupal 8.x

I have a site with Drupal 8 and the Flag module.

I would like to display a text when the user has the `association` role and when it is flagged with the following flag (his machine name):

flag_role_association

Then put its 2 conditions in a single line and how to know if the user is flagged ?

Here are my templates :

I am not a network engineer and my setup for a website is Drupal 8.9.x with Apache and PHP on Azure cloud.  The site was configured using the ip address until we could register a name which at some point was associated with the ip address.  When I try to login via the website name, the pages will be display as expected but the url will resolve to the ip address.  In Drupal 7, there was a base_url option in settings.php which I think is replaced by trusted_host_patterns in Drupal 8.  I've followed the example and entered in the ip address and the website name, but still my site will resolve/

I created a book with the module provided by Drupal 8, but I am unable to organize the pages of the book correctly in a view.

I want to organize the book in this way.

In the left block, pages and sub-pages are correctly organized, but in the content (it's a view), pages and subpages don't match my ranking.

I have a page (form) that I've created a twig template for, it's called `form--edit-communication-method-form.html.twig`, it loads in my actual form items as well as some other markup to polish everything up. However, now I need to present this form in a modal, and I'm attempting to do so by loading the form like so

I want to have an ID in my URL and the controller of my module should take the ID from the URL and display it. If the ID is changed in the browser and the side is reloaded, the page should print out the new ID. My problem is, that I can't get the ID out of the URL.

Example: /node/31?id=930bcae8-f8e5-491f-84fc-cdf104ca7e40

I have tried to following lines of code, to get the id and print it out:

'text' => \Drupal::request()->query->all(), <- prints out nothing
