What is the correct way to format the security scheme for Firebase using oauth 2.0 and OpenAPI 3.0?
The current documentation at https://cloud.google.com/endpoints/docs/openapi/authenticating-users-firebase is intended for OpenAPI 2.0, but not for OpenAPI 3.0.
I have reviewed the swagger documentation for OpenAPI 3.0, at https://swagger.io/docs/specification/authentication/, and I also came across a similar question at Swagger definition for firebase authentication, but again, the suggested answers point to OpenAPI 2.0, rather than 3.0
