Configuring api-platform to include header in OpenAPI (AKA Swagger) documentation

Question

I am using API-Platform with JWTs and have created a decorator to allow Swagger to display a /authentication_token endpoint as described by https://api-platform.com/docs/core/jwt/ and to a lesser degree https://api-platform.com/docs/core/openapi/. In addition to providing an email and password, I also need to provide a third parameter which is a UUID which identifies the account the user belongs to. I was able to do so by including the UUID in the body, but I would rather have it included as a header such as X-Account-UUID.

How can this be modified so that Swagger-UI includes this uuid property as a header and not in the body's JSON?
