How do I load CSS from node_modules dynamically?

loadFont(font: Font) {
      if (state.fontsToLoad.includes(font)) return

      switch (font) {
        case "poppins": {
          import("@fontsource/poppins/index.css")
          import("@fontsource/poppins/400.css")
          import("@fontsource/poppins/700.css")
          break
        }
        case "open-sans": {
          import("@fontsource/open-sans/index.css")
          import("@fontsource/open-sans/400.css")
          import("@fontsource/open-sans/700.css")
          break
        }
      }

      state.fontsToLoad = [...state.fontsToLoad, font]
    },
