Switch styles with variables in components

[Kurosaakii]

Hi!

For a new project we intend to use Material as per design system. For this purpose I duplicated the file from the community because of the need of theme personalization, but I don't understand how I could apply the local variables to the components in the file. The file contains both styles and variables, but the components have only styles applied. Due to this, I cannot switch between themes (light, dark, ecc). I checked the theme builder plugin but I didn't see anything related to the switch to variables in components.

How could I apply the updated local variables to components without losing a week of work???

Thanks!
