Voice commands Waze and Google Maps

Hello, I have a question/ problem.  When navigating through voice with Waze or Google Maps, Chigee uses the iPhone's microphone and not that of the (Senna) headset.  So navigating while riding with Google/ Waze voice command does not work. Because my phone is in my pocket. But when navigating with Siri, the microphone of my headset is used. Is there a fix for this issue?  Or is this the way it should be?
