Is there a simple way to use in any project ?

[Soltus]

I am not using a Vue project. I tried the method of README without effect, and another similar project can be simply used in my project:

import { useToast } from 'vue-toast-notification';
import 'vue-toast-notification/dist/theme-sugar.css';

export function exApp1() {
  // not need create a VUE app
  const $toast = useToast();
  window.__toast = $toast;
}

But this project has only a simple notification function, so I still want to use vue-toastification
