Disable 3 finger lookup in NSView using Swift

I am creating an online assessment application for Mac OSX in which there is a WebView which loads the assessment page. I need this application to be secure and hence require that the three finger tap which brings up the Lookup option in a Mac be disabled. I am unable to figure out how to do it. Held needed urgently. (Note: Its a Mac OSX application and not an IOS application so no UIView solutions please). Thanks.
