Last time I checked a few years ago embedding Google Maps in a web site was only free if the web site was publically available to all. But paid for licensing is needed if there's any security to restrict its usage to certain people.
You can try by implementing the Google API in qliksense mashups using API key. Up to certain times per day it is allowed to use, after that you have to pay. I have implemented the Google Distance matrix API up to certain extent.
