How to add size property to catplot kind point in seaborn?

Question

I have generated a seaborn catplot with kind=point as follows:

ax = sns.catplot(
    x     =  "bins",
    y     =  "sigma",
    hue   =  "conditions",
    data  =  DB,
    col_wrap = 2,
    errorbar = "sd",
    col_order = ["V1d", "V1v", "V2d", "V2v", "V3a", "V3v", "V5", "V4", "V3d"],
    kind  =  "point",
    palette = HUE_COLORS,
    col   =  "rois",
    dodge = False,
    join = False,
    scale = 1.5,
)

data is taken from "DB" database. "bins" is the x categorical variable (type string) while "sigma" the y independent variable (type float).
The plot is divided into several subplot defined with the "rois" variable for col.

Image from one roi

I would like each point to have different size depending on the "sigma" value (i.e., the bigger the sigma the bigger the point).

I managed to do so using the scatterplot plot, that in turn, does not have the error bars, which I need.

Is there a way to add the size property to catplot with kind as point? Thank you all!

• The answers provided here do not solve my issue. They work only with plain catplot, but when I add kind=point it doesn't work.
• The answer provided here does not help. The object does not contain "collections" property.
