Define bearerAuth in openAPI 2

Hi I have this security schema in OAS 3 that I'd like to translate to OAS 2, my understanding is that the security definition for bearAuth doesn't exist in OAS2 as 

a standalone but it is included as Auth2.0 access token, I have an api that takes in a jwt token that includes some information about the user then makes a call to an authorisation gateway using a payload X, this is what the model looks like in OAS 3 (reason I want to do this is beacause I'm using https://github.com/swaggo/swag#security for generating swagger spec in go and it doesn't seem to directly support OAS 3):

security:
  - bearerAuth: [ ]
components:
  securitySchemes:
    bearerAuth:
      type: http
      scheme: bearer
      bearerFormat: jwt
