Looking for a BBQ thermometer, Inkbird ibt-6xs is it supported?

Om looking at Inkbird thermometers and noticed that the native integration supports the 2x and the 4xs but not 6xs.
Is this correct? When I read from old EAP-Home threads it seems the same code can read from at least the 6xs and the 4xs.
So this makes me a bit confused. Anyone know if the 6xs works with native integration or if an ESP32 is required?
