Remap data from Polar Stereographic projection to Lat-Lon

I have a NetCDF file with storm track density data over south polar stereographic projection. Both X and Y coordinates range from -1.924274 to 1.88504 (I don't know the units here). The link for the .nc file is here.

When I open the file with Xarray and plot the data, I have the following: enter image description here

Is there any way to remap this to lat-lon grid in Python or CDO? Thanks!

You can probably do this using my package nctoolkit (https://nctoolkit.readthedocs.io/en/latest/), which uses CDO as a back end.

import nctoolkit as nc
data = nc.open_data("infile.nc")
data.to_latlon(lon = [lon_min, lon_max], lat = [lat_min, lat_max])
data.plot()

You will need to define lon_min etc.
