"Finds" is far too generous. There was no experimental research done. It was structure prediction using AI.
I'm starting to see a pattern with DeepMind and the quality of their papers.

>candidate structures filtered using GNoME are evaluated using DFT calculations with standardized settings from the Materials Project. Resulting energies of relaxed structures not only verify the stability of crystal structures but are also incorporated into the iterative active-learning workflow as further training data and structures for candidate generation
