Which ICON grid files are supported? _G.nc not working.

[skmue]

I am trying to make use of icon_uxarray, like:

`import uxarray as ux
from icon_uxarray import icon_grid_2_ugrid

gridfile = workdir_gridfiles+'icon_grid_0006_R03B07_G.nc'
hsurfile = workdir_gridfiles+'icon_global_icosahedral_time-invariant_2024060600_HSURF.nc'

ugrid_fname = icon_grid_2_ugrid(gridfile)

uxdata = ux.open_dataset(ugrid_fname,hsurfile)
`

But I get "KeyError: 'n_edge'"

Any help molst welcome!
