Thread:Support/Language names

Were can I localise interwiki language names for the Dutch Low Saxon Wikipedia? It currently uses the Dutch/untranslated names. For example: Duits = Duuts, Pälzisch = Paltsies, Cymraeg = Kumries, Kölsch = Ripuaries, Laagduits = Nedersaksies (Duutslaand). I see our German neighbours (German Low Saxon) have a (partly) localised version.
