Help me make astal widgets work

This is the wiki of astal widgets which I wan’t to use in my system: astal

This is the flake I have created: aoi
Now, I want that I make a home manager module (which I have hm-module.nix) So from there, If I import this whole flake in my nixos config which is in this repo https://gihtub.com/mobsenpai/hana, I can make use of the color options to give colors to aoi(astal) flake/package/folder right? So that is done, but now I would like a way in which I can actually edit the ‘scss/themes/astel.scss’ in (aoi) file based on these colors option which I will give.
