How to refer response header in client generate api #2814

I have defined the swagger in order to get the authorization token from the response header which can be used for next api call. However when I generate the client code out of swagger, it return only response body and not the header. I Have tried all the search but nothing was helpful.

Part of the swagger definition,

/token':
post:
tags:
- Token
parameters:
- $ref: '#/components/parameters/Authorization'
description: Used to generate token to call other api
operationId: generateToken
responses:
'200':
description: OK
content:
Application/Json:
schema:
type: array
items:
$ref: '#/components/schemas/XYZ'
headers:
authorization:
schema:
type: string

components:
parameters:
Authorization:
in: header
name: Authorization
description: Bearer token to access the one view API's.
schema:
type: string
required: true

Client Api generate: ( the method body doesnt have any code for response header"
public CompletableFuture<List> generateToken (String authorization) throws ApiException {
....
...}

If you could provide any insight that would be more helpfull
