Hi, I'm working with next/og, next/font/google and tailwindcss experimental implementation, however font.className is not being applied to the text when imported to the route.ts

Here's the playground for the tailwindcss implementation:
https://og-playground.vercel.app/

Here's my font configuration:

import {Poppins} from 'next/font/google'

export const poppins = Poppins({
subsets: ['latin'],
weight: '400',
variable: '--font-poppins',
})
