What I’ve gathered from many of the discussions around this topic is that thr levitation is a notable feature of superconductors due to th Meissner(?) Effect. So if it couldnt levitate, there would be no reason to suspect that it is a superconductor. Because it does levitate, superconductivity is one of a few possibilities.

There have been indicators it may be a semiconductor instead, but apparently the conditions to accirately produce the material are vague/not fully understood - so attempts at reproduction have failed to rule it in or out 100%
