I have a bar chart and I made some edits to the legend, but there is one I'm struggling to add in.

I have an onClick action that makes the chart only show one dataset and I put the sum of the dataset values next to the legend labels using generateLabels, and all I need now is to make the unselected labels become a lighter tone of color instead of having a strikethrough line but I've been looking everywhere for a solution but I can't find it.

This is the chart I'm working on: https://codesandbox.io/s/agitated-christian-0byxz
