Add sweet alert 2 to nuxt3 project

I'm struggling to integrate sweet alert 2 as a plugin into a nuxt3 app. I'm trying to use vue-sweetalert2 but I at some point it define global variables.

// Inside the install function
vue.prototype.$swal = swalFunction;
vue['swal'] = swalFunction;

Could you please help me, how to access these global variable? The documentation do not show that.

I guess the goal would be to have inside my plugin something like:

import VueSweetalert2 from 'vue-sweetalert2';
import 'sweetalert2/dist/sweetalert2.min.css';

export default defineNuxtPlugin((nuxtApp) => {
  nuxtApp.vueApp.use(VueSweetalert2)

  return {
    provide: {
      swal: swalFunction // <- how to access this ?
    }
  }
})

I'm learning nuxt3 too.Here is how I use sweet alert 2 in my app of nuxt3.

plugins/swal.js

import Swal from "sweetalert2";
import "@sweetalert2/theme-bootstrap-4";
const $swal = {
    install: (Vue, options) => {
        Vue.config.globalProperties.$swal = Swal.mixin(options);
    },
}
export default defineNuxtPlugin((nuxtApp) => {
    nuxtApp.vueApp.use($swal, {
        reverseButtons: true,
        confirmButtonText: "confirmText",
        cancelButtonText: "cancelText",
        confirmButtonColor: "#84bd00",
    });
});

Usage in components

<script>
    export default {
      const fn = getCurrentInstance().appContext.config.globalProperties;
      fn.$swal.fire({
          title: "hello",
          timer: 2000,
      });
    }
</script>

Or use by provide and inject, My plugins/swal.js will be like this.

import Swal from "sweetalert2";
import "@sweetalert2/theme-bootstrap-4";
const options = {
    reverseButtons: true,
    confirmButtonText: "confirmText",
    cancelButtonText: "cancelText",
    confirmButtonColor: "#84bd00",
}
const $swal = {
    install: (Vue, options) => {
        Vue.provide("$swal", Swal.mixin(options));
    },
}
export default defineNuxtPlugin((nuxtApp) => {
    nuxtApp.vueApp.use($swal, options);
});

Usage in components

<script>
    export default {
      const swal = inject("$swal");
      swal.fire({
          title: "hello",
          timer: 2000,
      });
    }
</script>

Hope it's helpful.
