Google Analytics Hover Event Tracking

This is how I'm tracking on click events with GA Universal Analytics. How do I do this with hover?

ga('send', 'event', 'button', 'click', {'nonInteraction': 1, 'eventLabel': 'bottom-cta', 'page': document.URL, 'eventValue': 0});

is it just this?

ga('send', 'event', 'button', 'hover', {'nonInteraction': 1, 'eventLabel': 'bottom-cta', 'page': document.URL, 'eventValue': 0});
