VS Code syntax highlighting for template string css? (Emotion) [duplicate]

How do I enable syntax highlighting for emotion template string css in VS Code? All the plugins I find are for snippets.

It works with css({ camelCaseCssProps:...}) but I am trying to use css variables for theming without imports and I guess in general I'd rather keep the regular kebab-case css syntax in my global styles file:

// index.js
    
render(
  <Global
    styles={css`
      html {
        // css variables (and/or camel-case props)
        --color-base: white;
        --color-text: #434449;
       }
    `}
  />
)
