Hi Cédric, we use the woo_ce_get_user_roles() to populate our Filter Users by User Role dropdown in our Pro Plugin.

Upgrading to the Pro Plugin will unlock this functionality, I’ve made a note to move this feature to the free Plugin too but this will happen when I have some free time from supporting our Pro community 🙂
