For the first time, due to a higher angular resolution than previous studies, we clearly detected dense molecular gas emission at the putative AGN location, identified as a ~1.1 mm (~266 GHz) continuum emission peak, by separating this emission from brighter emission located at 0.5-2.0 arcsec on the eastern and western sides of the AGN.
