Named Export from CommonJS module fails

When using https://github.com/Maronato/vue-toastification#using-a-custom-component

like (in modules):

import type { PluginOptions } from 'vue-toastification'
import Toast, { POSITION } from 'vue-toastification'
import type { UserModule } from '~/types'
import 'vue-toastification/dist/index.css'

export const install: UserModule = ({ app, isClient }) => {
  if (!isClient) return
  const options: PluginOptions = {
    position: POSITION.BOTTOM_RIGHT,
    timeout: false,
  }
  app.use(Toast, options)
}

And build, I get:

[vite-ssg] Build for server...

import Toast, { POSITION, useToast, TYPE } from "vue-toastification";
                ^^^^^^^^
SyntaxError: Named export 'POSITION' not found. The requested module 'vue-toastification' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'vue-toastification';
const { POSITION, useToast, TYPE } = pkg;
