worked for me: https://github.com/morewings/storybook-addon-theme-provider

preview.ts:

 decorators: [
    withThemeProvider(Provider),
    ///...
  ],

Provider.tsx:

export const Provider = <TTheme,>({
  children,
  theme,
}: {
  children?: ReactNode
  theme?: TTheme
}) => {
  return (
    <ThemeProvider theme={theme as DefaultTheme}>
      <GlobalStyles />
      {children}
    </ThemeProvider>
  )
}
