How Do You Enable The Wake Word On The AVS-device-SDK?

  alexa, alexa-voice-service, c++

I am trying to build an app that is Alexa-enabled and would like to enable the wake word engine (WWE) but can’t seem to find how to do so. The Amazon Developer website states that you have to change the client code but I do not understand which part of the code that is. Does anybody know which part I need to edit?
