Download new Allen Human-mouse-marmoset dataset

Hello,

I am interested in downloading the datasets associated with this study published yesterday Comparative cellular analysis of motor cortex in human, marmoset and mouse | Nature

Data availability statement indicated to look into the following link:
https://assets.nemoarchive.org/dat-ek5dbmu

It appears that the source data url is empty here

Any idea when this will be made available or alternate links to access this dataset?

Thanks and regards,
