Center Gallery Thumbnails

I noticed the thumbnails on all our galleries are left justified and our layout would look cleaner if they were centered. Is there a setting that I’m missing that can left, right, or center them? I’m using the plugin with Elementor and none of the Elementor centering tools are working which makes me think the layout is being controlled by Photonic.

Here is a link to a screenshot help you see what I’m trying to articulate: https://goflashwin.com/wp-content/uploads/2022/09/justified-screenshot.jpg

Thanks for all your help!
