dis able the Expand Buttom

Hi

I would like to disable completely the Expand Button
It looks like a button to “close” the lightbox image, but intuitively, folks click it, hoping to go back to normal view, but instead, go another level deeper

And, in the Settings, it says you can control the Expand Button, but there is no checkbox

I love the plugin overall, just hoping to find a way to disable the expand button
