Using extend.ts Tokens from Generated Theme

[hinducows]

I have custom tokens in my custom theme that get added into an extend.ts file. I know for certain the application is correctly referencing this file because my primary color, which is a custom token, is showing correctly.

But my question is: How do I get the non-color tokens to apply to their components?

For example if I have the following custom token to set the height for an icon-only button:

button: {
    icon: {
        only: {
            height: "2.5rem"
        }
    }
}

For what it's worth I'm using the CI pipeline to generate my custom theme, and nothing that exists in the theme files, including the extend.ts file, is being modified afterwards.

Thanks for any and all help!
