Another handy extension to Swashbuckle which I have written displays which endpoints have Authorization, and which policies, roles, or users have access to that endpoint.
You can get it by installing either my Swashbuckle.Examples or Swashbuckle.AspNetCore.Examples NuGet packages.
Installation instructions etc are at the above links.
