+ * 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.
