Why default language doesn't redirect me to /fa?

Question

import { defineI18n } from "fumadocs-core/i18n";
export const i18n = defineI18n({
 defaultLanguage: "fa",
 languages: ["en", "fa", "cn"],
 fallbackLanguage: "fa",
 parser: "dir",
});

Here is my i18n config
But It doesn't redirect me to the localhost:3000/fa based on the defaultLanguage
Do you have any useful way to solve this?
