From that article:

“The general public seems oddly pumped about how ‘easy’ the 4-day, multistep, small batch, solid state synthesis is,”

The process is a 3-stage heating-holding-cooling process which they haven't published the precise temperature profile for. The papers also claim only 4 samples were ever made in total, 2 of them got (destructively) analyzed by gas spectroscopy and crystallography, while of the other 2, one got further temperature annealed, and both got electrically characterized.

Chances are, they themselves don't know exactly how they got what they got, and may or may not be capable of producing more samples.
