I ran into this the other day, I’m not sure about the sound of it, but that’s more likely the setup he used.

It’s a bit strange that this Alice has better traits than the Akko Alice. It’s not a complete kit, but still. You get south-facing PCB, GMK/VIA support, the cable comes out of the center (which looks a lot better IMO), and you get proper legs (which are also adjustable). I mean, Akko included these silly legs that you have to double-side tape onto the bottom of the keyboard arbitrarily.
