Carbon Design System in a Workspace

[armper]

Hello, I'm trying to get carbon design system working for a project within a workspace application.
I can enable carbon design system within a new Angular v 15 app just fine but when I do the same steps for a workspace, the styles don't have any effect.

Here is my example workspace Angular application: https://github.com/armper/test-cds-workspace
Here it is on Stackblitz https://stackblitz.com/~/github.com/armper/test-cds-workspace
