I have a very basic question, just trying out htmx. I have a button:

<button 
  hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}'
  hx-post="{% url "listings:listing-favorite" listing.slug %}"
>
  Some text
</button>

the post view returns some json like

{"added": id}

or

{"removed": id}

I would like to toggle a class on the button if the response is

{"added": id}

. Is it possible to do?
