如何串联url（&#39; <front> &#39;）+ Twig drupal中的字符串

Question

I am trying to select a path that is equal to (http: // myweb / app) in html.html.twig of drupal.

For this, I'm using URL, but when trying to concatenate an array (which would be url ('<front>') with a string returns ArrayString) obviously this is wrong.

{% set url_app_front = url('<front>') %}
{% set url_app = url_app_front ~ 'app' %}

Arrayapp

It is clear that url('<front>') is an array, but the #Markup that returns clean is http: / myweb /. I have tried to select it but... dont know how.

{{ url('<front>').markup }}

What I'm looking for would be something like ...

{% set url_app = url('<front>') ~ 'app' %}
{% set url = url('<current>') %}
{% if '{{ url_app }}' in url|render|render %}

To select http://myweb/app

If there is any other way to achieve it, I am also willing to read

We have to convert this array to a string (thanks to #markup) with render_var()

I got it in https://drupal.stackexchange.com/questions/243648/concatenate-url-in-twig (my bad for not looking there first)

{% set url_app = render_var(url('<front>')) ~ 'app' %}
{% set url = url('<current>') %}
{% if url_app in url|render|render %}
....
{% endif %}

http://myweb/app
