How to retrieve density value from seaborn 2D histplot

I use sns.histplot to make 2D density plot. For example

sns.histplot(x=e, y=costheta, bins=50,
             cmap=plt.cm.coolwarm,
             binrange=[[0,1.05],[-1,1]],
             stat="probability",
             thresh=1e-5,
             norm=mpl.colors.LogNorm(1e-5,1e-2),
             vmin=None,vmax=None)

where e and costheta are my data.

Now I want to get the density value of each coordinate from this plot. What should I do?
