Add onsubmit or similar

[omgslinux]

I'm working on a basic crud with ux-live components, and have a problem with the code in the "delete" link next to "edit" for each row.

The usual code, as you should know, generated with make:crud for a "question" entity is like this:

<form method="post" action="{{ path('app_question_delete', {'id': question.id}) }}" onsubmit="return confirm('Are you sure you want to delete this item?');">
    <input type="hidden" name="_token" value="{{ csrf_token('delete' ~ question.id) }}">
    <button class="btn">Delete</button>
</form>

So, I'm looking for a way to have a way as a parameter to {{ live_action () }} to have a similar behaviour.

Is there already something I'm missing (except stimulus code) or should be added?

Thanks in advance.
