How to create contour plot in R which with the color in each contour scaled separately by the density of all points within the contour

Question

I am trying to create a contour plot in R in which all points in a certain contour are scaled according to the density inside that contour, not with respect to the density of all points in total. For example, I am trying to replicate a plot like this: https://docs.flowjo.com/flowjo/graphs-and-gating/data-visualization-and-display/gw-zebra/.

I am not sure where to proceed in doing so. If anyone could provide any advice, that would be greatly appreciated.
