def permission_to_model_action(permission)
  #
  # Permissions are defined in Kill Kill apis (https://github.com/killbill/killbill-api/blob/master/src/main/java/org/killbill/billing/security/Permission.java)
  # and they look something like 'invoice:item_adjust' or 'payment:refund', where the first part is the Kill Bill module and the second the action.
  #
  # For most of those the Kill Bill module maps to the Kaui model, but for a few, the naming convention breaks, so in order to keep the API clean, we do the fix up
  # in KAUI itself:
  #
  to_be_model, action = permission.split(':')
  # Currently the only actions implemented for overdue and catalog (upload_config) are those implemented at the tenant level:
  if %w(tenant overdue catalog).include?(to_be_model)
    to_be_model = 'admin_tenant'
  end
  if to_be_model == 'entitlement'
    to_be_model = 'subscription'
  end

  [to_be_model, action]
end
