MobileCore callbacks

I can’t seem to find any onAdClicked callbacks for MobileCore interstitials. Anyone figure out a way how to process clicks with MobileCore?
Also, there’s no manual way to fetch ads, is there? The entire ad fetching and showing process is aggregated in showInterstitial from what I gather. Surely this isn’t the best approach to handling video ads. Did anyone actually get any video ads? Their guide says they are supported, but their sdk leaves thinking otherwise.
