@intlify/unplugin-vue-i18n doesn't work properly on library mode build

[Byndasp]

Using vite enviroment localization works properly
But when build as library i've got an error TypeError: x.$t is not a function

Vite config

import vue from '@vitejs/plugin-vue'
import VueI18nPlugin from "@intlify/unplugin-vue-i18n/vite"
import {defineConfig} from 'vite'

import * as path from 'path'

module.exports = defineConfig(({mode}) => {
    return {
        plugins: [
            vue(),
            VueI18nPlugin({
                include: [path.resolve(__dirname, './src/locales/**')],
                strictMessage: false
            })
        ],
        build: {
            lib: {
                entry: path.resolve(__dirname, 'lib/main.ts'),
                name: 'VuePlugin',
                fileName: format => `vue-component.${format}.js`
            }
        }
    }
})

Entry point:

import {createApp} from 'vue'
import messages from "@intlify/unplugin-vue-i18n/messages"
import {createI18n} from "vue-i18n"

import App from './App.vue'

const lang = document.documentElement.getAttribute('lang')
const currentLang = lang ? lang.substring(0, 2).toLowerCase() : "de";

const i18n = createI18n({
    legacy: false,
    globalInjection: true,
    locale: currentLang,
    fallbackLocale: "de",
    messages: messages,
});

const app = createApp(App)

app.use(i18n)
app.mount('#app')
