How can I move the styles from the file to the style tag of the header?

Question

webpack

I enabled extractCss: true in nuxt.config so that all styles are connected via a link and the browser can cache them. But the problem is that when the page is reloaded, bare html is first visible, and after a moment the styles are loaded and the layout becomes correct. I moved the styles that are necessary for correct layout to a separate critical.css file. You need to add the styles from this file inline to the style tag. How can this be implemented?
