ZTF have now called it on TNS as a type II based on a spectrum they took 5 days ago. I would not say  their spectrum is over convincing though (A hint of a broad H alpha emission at the galaxy redshift, perhaps with a P Cygni profile but not much else) and running it through SNID does not come up with any high confidence hits. It shows a blue continuum suggesting not much IS extinction so it seems to be very much at the low luminosity end

Cheers
