Add sharing links to each image ina TagDiv Slide Gallery

I need to insert sharing icons to each of the any number of images a TagDiv Slide Gallery can have.

Digging Newspaper’s files I found td_wp_booster_functions.php and the function td_gallery_shortcode. I tried to override this function from a child theme to add the icons to the variable $slide_display_html, no luck so far.

So how exactly can I get this done from a Newspaper’s child theme?

Note to make things clear:
This question is NOT about the regular post/cpt sharing icons, whose settings are on Theme Panel under Post Settings > Sharing. Before someone makes any weird assumption regarding what I’m asking here.
