Purgecss removes imported styles, how to fix?

Question

css

To remove unused styles, I use PurgeCSS, or rather the webpack module.
The problem is that it removes the styles of the Flatpickr datapicker plugin.
Styles are connected via import (View template)

import FlatPickr from 'vue-flatpickr-component'
import { Russian } from 'flatpickr/dist/l10n/ru.js'
import 'flatpickr/dist/flatpickr.css'

Answer 1

Well, you read its settings then. There are patterns, whitelist, indication of specific files.
