How to Center Output of Shortcode?

I don’t believe this is natively available, but it very well may be. I want to center the output of a shortcode, specifically from the below plugin:

The plugin’s shortcodes do not have the option to have allignment center of the profile boxes, so I was thinking that I could possibly just set the allignment of the output itself to center without having to have the specific feature in the plugin? Or is there a way to make a frame (borderless) in center of top of page and just put the shortcode in it?

Basically, I have changed the shortcode’s # of columns value to “1” so that I can have one person’s picture and name in the little profile boxes created by the plugin, but the default allignment is left and have no clear way of changing, but still want to so looking for “hacky” or hardcoded solutions.

Please respond ASAP. Thanks in advance.
