Optiq and Heat Pump

If no one can confirm whether the Optiq does or does not have a heat pump, can you suggest who to ask? I asked the dealer and several forums including ChatGTP and MS co-Pilot. The dealer doesn’t know, and some AI responses say yes and others say no. I am beginning to think I can’t get a firm answer because GM decided not to include a heat pump. Which I think would be a bad decision for customers living in cold climates. The mechanical spec sheet should state how the cabin is heated and the BMS battery temperature is controlled. The answer would either be a resistance heater such as PTC OR a heat pump and resistance heater. That would be seen as transparent marketing.
