TW is not defined

[WebTerminator]

I have a Next.js app setup with TS, Tailwind and Styled-Components. Storybook and the application work fine in displaying my components however my tests are failing:

my component:
export const HamburgerIconWrapper = tw.div flex flex-1 justify-start sm:hidden

my test:

test("renders HamburgerIconWrapper snapshot", async () => {
    let renderedComp
    await act(async () => {
        renderedComp = render(<HamburgerIconWrapper />)
    })
    expect(renderedComp.asFragment()).toMatchSnapshot()
})

Result:
