dears,
I recently created a slider with a repeating group, it works all fine, but there is a missing fonctionality that i couldn’t figure out how to emplement, which is changing the color of bollet points that are corresponding to each cell of the repeating group when we scroll horizontally,

in the image above, i scrolled with the thankpad to the first element, but the bulletpoint color is still showing the last item of the repeating group, as i manage it’s color thru a custome state , so i need to know if there is a possibility to chage a custome state when we scroll inside a repeating group
thanks by advance
