interactive circle: center clickable ?

very nice plugin. A nice mix between the free and the paid features. And the duplicate post/CPT feature works better than any other.
My question for the interactive circle: how to make the center clickable (to same URL target) once selected by mouse-hover ? It’s a bit the shame as this area is logic to click and is way bigger in surface than the external icon.
What should I change in the code ?
(currently only the external icon links to the final URL; my question is specifically for preset #2, but likely similar for others)
