I have the following stack: Ngnix -> API Gateway -> Lambda (Integration Type)

On the Nginx configuration file, I am using the following directive: proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

When I'm checking logs,

1. In API Gateway logs I see the load balancer IP
2. In Lambda logs I do have access to the X-Forwarded-For header

My question: How can I add to API Gateway Logs the X-Forwarded-For header with its value, or even better, replace sourceIP value with the one we are forwarding.
