Discrepancy between AWS Architecture Icons and AWS Arch package in this project

[usrlocl]

AWS Arch package description says it generates mappings to AWS Architecture Icons (https://aws.amazon.com/architecture/icons/), but I see a discrepancy in the paths returned from the package compared to the directory structure of the icons package. The icon package also seems to have more assets with different sizes like 16, 32, 48 etc. which doesn't reflect in what is returned here.

Not sure if I'm missing something, what's the correct way to use this package. Do I need to work with assets packaged within this package itself or is there some way to configure this to work with the icon package provided at AWS Architecture Icons?
