No Grid Orders class in TailwindCSS v3.4.3 on npm release ?

[FlogFr]

Hello,
I'm working with a HTML / CSS / JS template with tailwindcss v3.4.3 installed from yarn / npm.
I would like to use the Order Grid feature.
In the related TGZ of the release downloaded : https://registry.yarnpkg.com/tailwindcss/-/tailwindcss-3.4.3.tgz#be48f5283df77dfced705451319a5dffb8621519
I don't see any results on grep for order-last class.
Could you point me to where am I doing something wrong ?
Thank you

You wouldn't see the order-last class name in the package itself. If you use the class name in a file covered by the Tailwind config content file globs, the CSS rule should be compiled into your output CSS file.
