How to add Custom Interceptors In OpenAI Java SDK

How to add Custom Interceptors In OpenAI Java SDK when using response API?
All i Can do is
OpenAIOkHttpClient.builder()
.apiKey(“Keys”)
.timeout(Duration.ofSeconds(300))
.maxRetries(3)
.responseValidation(true)
.build()

But i want to add custom headers so i can track remaing requests and then throttle accordingly
Any help is appriciated!

FYI i am using 2.12 Version
