TWebGMapsGeocoding & APIKey

We are using the TWebGMapsGeocoding component to get a lat/long from an address. Works a charm (thanks for the good work). 


However, unlike the TWebGMaps which allows the setting of a Google APIKey, we cannot set a key on the TWebGMapsGeocoding. When using the component, nothing shows up on our Google's Dashboard API Console (yes we do have that particular API turned on -  Google Maps Geocoding API) . I noticed a ClientID property but that wasn't it either. 

My questions:
1) What is the ClientID used for?
2) How can I (or can I) set an APIKey for the TWebGMapsGeocoding component?
3) What can we do to track traffic on the Google console using TWebGMapsGeocoding?

Thanks in advance,
Richard

I also tried setting WebGMapsGeocoding.PrivateKey, didn't work either. 

What is the WebGMapsGeocoding.PrivateKey used for?

If you have a Google Maps premium plan, you need to set both the obtained ClientID & PrivateKey.
