It is pretty cool, but it’s a bit misleading… They didn’t ‘see’ dark matter, because it doesn’t interact with light or any particles. But they detected weak gravitational lensing caused by the dark matter (or any alternative source of the gravity we’ve coined dark matter), so this is not really conclusive physical evidence of dark matter.
But I’m no expert, please let people with astrophysics background correct me if I’m wrong.
