- * ApplicationsMenu Component
- *
- * This component is a work in progress (WIP) and serves as a proof of concept (POC) to showcase a future advanced feature.
- * The purpose of this component is to render an applications menu for La Suite, allowing users to switch between different La Suite apps seamlessly.
- * To ensure synchronized content across applications, it utilizes an iframe hosted on Scalingo.
- *
- * This PoC has been created by @manuhabitela.
- *
- * It includes external CSS and JavaScript files for styling and functionality.
- *
- * Style has to be included as well: https://suite-numerique-gaufre.osc-fr1.scalingo.io/public/styles/gaufre-vanilla.css \
- * To respect next.js standards, the css is included using the `_document.ts` component.
