Connected via yarn using the commands:
yarn add @fortawesome/fontawesome
yarn add @fortawesome/free-regular-svg-icons
yarn add @fortawesome/free-solid-svg-icons
yarn add @fortawesome/free-brands-svg-icons
inserted into JS
import fontawesome from '@fortawesome/fontawesome'
import regular from '@fortawesome/free-regular-svg-icons'
import solid from '@fortawesome/free-solid-svg-icons'
import brands from '@fortawesome/free-brands -svg-icons'
fontawesome.library.add(regular)
fontawesome.library.add(solid)
fontawesome.library.add(brands)
but still doesn't work
