How to declare correctly a route with facultative authentication in openApi 3.0 specification?

Question

I have a route that returns the content of a public article. If the user is logged, the route returns a different content (a content with additionnal details). I don't know how to declare this in my openApi definition. I couldn't find anything about this in the official doc.

My securitySchemes definition :

components:
  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT

My route declaration :

 /article/{slug}:
    get:
      tags:
        - articles
      summary: Return an article with more detail for authenticated users
      operationId: get_detail_article
      parameters:
        - name: slug
          in: path
          required: true
          schema:
            type: string
      security: 
        - {}
        - bearerAuth: []
      responses:
        "200":
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Article"

Is the authentification part is correct ?

the result in swagger editor :

As you can see, the lock at right is black and closed, meaning that authentification is necessary.

Not sure which Swagger Editor version you are using but the security object is defined correctly for an OR condition, as in.. must use bearerAuth OR none

openapi: 3.0.3
info:
  title: test
  version: 1.0.0
servers:
  - url: https://www.example.com
paths:
  "/article/{slug}":
    get:
      tags:
        - articles
      summary: Return an article with more detail for authenticated users
      operationId: get_detail_article
      parameters:
        - name: slug
          in: path
          required: true
          schema:
            type: string
      security:
        - {}
        - bearerAuth: []
      responses:
        "200":
          description: OK
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/Article"
components:
  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: JWT
  schemas:
    Article:
      description: An Article
      type: string

I get a transparent lock on Swagger UI free account

If I comment out the empty security, the lock changes to require only bearerAuth
