We want to create various user roles and have content restricted for frontend users based on which role(s) they’re in (We’re building a B2B marketplace with users grouped by, amongst other things, geography). I’m wondering how granular we can make permissions and/or if there are any limitations? Given Strapi is still a young project, does its user management/permissions allow for near limitless configurations like a Firebase or Drupal would? Or is it still evolving and there are indeed some limitations?
