Docusaurus Admonitions not working since upgrade from V2 to V3

Question

It was working on version 2, but from version 3, the admonitions are rendered in simple text, without the special design.

This is the package.json file:

{
  "name": "my-website",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "docusaurus": "docusaurus",

    "serve": "docusaurus serve",
    "write-translations": "docusaurus write-translations",
    "write-heading-ids": "docusaurus write-heading-ids"
  },
  "dependencies": {

    "react-icons": "^4.3.1",
    "react-vertical-timeline-component": "^3.5.2"
  }
}
