Hi @gamma42 , at the moment we do not suppert A/B testing in the plugin itself yet. This can be something that we like to implement in the future. How would you like to see this implemented?
A possible solution for now is giving both groups/buttons a different classnames. Then you are able to hide buttons or groups based on their classes. You'll need to do the A/B check on your own side in this case, but it's definitely possible 🙂
