After the process is started (the process is still running), you can refresh the ui after modifying the information in the configuration file locally to display the locally updated parameter information in the configuration file

To ensure the latest settings of the configuration file are reflected in the UI after a refresh in hugegraph_llm.demo.rag_demo.app, you should use the apply_*_config functions. These functions update the settings and call settings.update_env() to apply the changes.

For example, when you click the "apply configuration" button for embeddings, it triggers the apply_embedding_config function, which updates the settings and calls settings.update_env(). This ensures that the latest settings are applied and reflected in the UI.

Make sure to call the appropriate apply_*_config function for each configuration section to update the settings and reflect them in the UI ^[1].
