+5. **Add required provider fields to the settings**
+ClassifAI uses a React-based settings panel. To add the necessary provider fields, include the following code in a JavaScript file, and save it within your plugin's directory.
+
+_**Note:** The provided code snippet uses modern JavaScript (ESNext and JSX), which requires a build step to compile it into a browser-compatible format. We recommend using the [@wordpress/scripts](https://www.npmjs.com/package/@wordpress/scripts) package to manage the build process. For a step-by-step guide on how to install and use this package, check out this tutorial: [Get started with wp-scripts](https://developer.wordpress.org/block-editor/getting-started/devenv/get-started-with-wp-scripts/)._

+ */
+function my_provider_enqueue_admin_assets( $hook_suffix ) {
+    // Enqueue assets only on the ClassifAI settings page.
+    if ( 'tools_page_classifai' !== $hook_suffix ) {
+        return;
+    }
+
+    $asset_file = include( plugin_dir_path( __FILE__ ) . 'build/index.asset.php');

+}

+## Use Legacy settings
+ClassifAI 3.2.0 introduces React-based settings and deprecates the PHP-based settings pages. If you have customizations in the legacy settings and would like to continue using the legacy settings panel, you can enable this by using the `classifai_use_legacy_settings_panel` filter hook.
+
+However, please note that legacy settings will be completely removed in future releases. We recommend updating your customizations to use the React-based settings panel. If you encounter any issues, feel free to report them on our [GitHub repository](https://github.com/10up/classifai/).
+
+Add the following snippet to your theme's `functions.php` file or a custom plugin.
+
+```php
+add_filter( 'classifai_use_legacy_settings_panel', '__return_true' );
+```
