Apple Watch Charger to USB-C Cable (0,3 m) MU9K2ZM/A fast charging support?

I came across MU9K2ZM/A when I was looking for a short Apple Watch charging cable for travelling. 0,3m sounds nice, however it seems this product was launched back in 2018, and I wonder whether fast charging is supported here, generally.

According to About fast charge on Apple Watch - Apple Support, USB-C magnetic fast charging cables can be identified from other chargers by the USB-C connector and the aluminum around the magnetic charger. Both seem to apply here.

Does Apple Watch Charger to USB-C Cable (0,3 m) MU9K2ZM/A support fast charging (with the respective power adapter and Apple Watch Series 7 or later)?
