Get selection from hvplot with Cartopy overlay


I’m trying to access selected points in a data frame of the format:

I’d then like to get a selection from that. I roughly followed this:

However, that didn’t seem to work. Here’s a minimal code:

scatter = df.hvplot.points(x="Longitude", y="Latitude", projection=ccrs.PlateCarree(), coastline=True, color="red", tools=["lasso_select", "poly_select"])
sel = hv.streams.Selection1D(source=scatter)

Any hints would be appreciated!!
