SDK logging — How to implement REST API logging in the Java SDK Demo Example?

The Kotlin part of the Java SDK uses the Fuel library for making HTTP calls. We have been able to make logging available by invoking following Fuel configuration prior to any call to the SDK. Note this may be subject to change in the future, when the SDK is planned to be refactored.

FuelManager
        .Companion
        .getInstance()
        .addRequestInterceptor(LogRequestAsCurlInterceptor.INSTANCE);
System.out.println("Fuel debug logging enabled");

Logs:
