Symfony 4 : AccessDeniedHttpException() get access custom variables - symfony

Question

In my RequestListener.php, if an entity is not accessible for a user, i use the following exception :
throw new AccessDeniedHttpException();
So it returns me my custom 403 error html template using twig.
<div class="jumbotron jumbotron-fluid exception">
<table class="wrapper">
<tr>
<td>
<div class="error-code">
<span>403</span>
<div class="caption">
<h1 class="text-light">Test h1</h1>
<h2 class="text-light">Test h2</h2>
<p>
Test
</p>
</div>
</div>
</td>
</tr>
</table>
</div>
Now what I want to do is, for the same :
throw new AccessDeniedHttpException();
Using different message depending on the situation where occurs the error 403.
For example what i tried to do is :
throw new AccessDeniedHttpException('custom');
In my template 403.html.twig
<div class="jumbotron jumbotron-fluid exception">
<table class="wrapper">
<tr>
<td>
{% if status_text %}
{{ status_text }}
{% else %}
<div class="error-code">
<span>403</span>
<div class="caption">
<h1 class="text-light">Test h1</h1>
<h2 class="text-light">Test h2</h2>
<p>
Test
</p>
</div>
</div>
{% endif %}
</td>
</tr>
</table>
But I don't know if the string passed in the exception is reachable in my error template...

Maybe have a look at this:

You can use the exception.message variable in twig.
<div class="jumbotron jumbotron-fluid exception">
<table class="wrapper">
<tr>
<td>
{% if exception.message %}
{{ exception.message }}
{% else %}
<div class="error-code">
<span>403</span>
<div class="caption">
<h1 class="text-light">Test h1</h1>
<h2 class="text-light">Test h2</h2>
<p>
Test
</p>
</div>
</div>
{% endif %}
</td>
</tr>
</table>
