Snapped swing arm

So today, my first time at Grenoside steel city I snapped my swing arm on my 2017 norco Fluid.
I’m a fat lad and the transition between berms didn’t agree with my bike. I can’t find anything online for spare parts, I assume I’m using the wrong terminology. Coukd someone please advise what the parts called so I can try and find a replacement. Although the diagram isn’t the same frame, it’s the same component as I’ve broken.
