Click on grouped/stacked bar chart

I have a grouped/stacked bar chart. Need to know which bar is clicked within a group/stack for the event ‘plotly_click’, e.g. if I have grouped bar chart that have 3 groups and within each group there are 5 bars(columns), I wan to know that’s it’s bar number 5 in group 3 is clicked, or something similar. Right know I can only know which group is clicked on using the ‘pointNumber’ with the click event data. Also would need similar thing with stacked bar chart. Thanks.
