Any Sigenergy V2X Supported Vehicles?

I have the Sigenergy DC EV charger and I'm looking for my next car which I want to be able to use as a big home battery.

There have been some sparse posts asking the same thing, but I could barely find any posts about people who had actually got an EV reliably exporting electricity. Has anyone had any success and, if so, did you face any issues or restrictions? Sigenergy has a compatibility list on their site, but it uses some very hardworking asterisks which mean I can't rely on it for what I want.

I don't have any solar or battery modules and I have a heat pump so we use about 50kWh on cold winter days hence the need for a battery much bigger than we could really get (or afford) in a home battery system. I'll be charging the car overnight when electric is much cheaper and discharging in the day so I don't need expensive electric from the grid.
