Hi Clientes,
Sorry, it's not possible for both cloneable and non-cloneable groups. We are working on it, but until now, there's no kind of drag & drop solution yet. The recommended way at the moment is using a custom shortcode to render the group and put it in Elementor.
You might also can try to reach out to Didou Schol on Meta Box Users group on Facebook (https://www.facebook.com/groups/metaboxusers/), he developed a Toolbox extension for Beaver Builder/Elementor that works with Meta Box Group. He might help on this.
