Description

Is your feature request related to a problem? Please describe.

Often, Open API specs contain a securitySchemes component (https://swagger.io/docs/specification/v3_0/authentication/) for authentication.
It would be great if the generated OCaml code supported passing authentication data (e.g., the Authorization header).
As a simpler but still quite useful alternative, if all endpoints accepted an optional list of header names and values, one could "easily" pass ~additional_headers:[("Authorization", "Bearer <token>")].

Describe the solution you'd like

Ability to pass authentication data.

Describe alternatives you've considered

Currently I have to copy the generated code to add those authentication headers 😢

Additional context

N/A.

Research direction

Start by locating the OCaml generator and its generated endpoint functions, then trace how OpenAPI securitySchemes are represented. Compare the requested authentication support with the simpler additional-headers alternative. Done means generated OCaml clients can pass authentication data, or optional headers, with coverage for the supported behavior.
