Using same slug on different locales

I have fixed by the following lifecycle addon:

By adding this lifecycle, when the slug fieldis is empty it will gen the slug from the title field, the slug will only genetrate in the en locale.

The slug field:

    "slug": {
      "pluginOptions": {
        "i18n": {
          "localized": false
        }
      },
      "type": "string",
      "unique": false,
      "regex": "^[a-z0-9]+(?:-[a-z0-9]+)*$"
    }

The lifecycle.js put under ./api/[api-name]/content-types/[content-type-name]/ folder, replace all api::blog.blog to api::[your-api-name]:

let slugify = require("slugify");
const { ApplicationError } = require("@strapi/utils").errors;

module.exports = {
  async beforeCreate(event) {
    await generateSlug(event);
  },

  async beforeUpdate(event) {
    await generateSlug(event);
  },
};

const generateSlug = async (event) => {
  const DEFAULT_LOCALE = "en";
  const { data } = event.params;
  const id = event.params?.where?.id ?? null;
  const locale = !id ? "en" : await getLocale(id);

  //Generate slug for en locale only
  if (!data.slug && data.title && locale == DEFAULT_LOCALE) {
    data.slug = slugify(data.title, { lower: true });
  }

  if (!data.slug) {
    throw new ApplicationError("Slug is required!");
  }
};

const getLocale = async (id) => {
  const res = await strapi.service("api::portfolio.portfolio").findOne(id);

  return res.locale;
};
