   Basic example of the hook for below operations.

   1. Updating the user meta with the new locale using the update_user_meta() function.
   2. Displaying a success message indicating the switched locale.

   // Define a callback function to execute when the switch_locale action is triggered
   function wpdocs_switch_locale_callback( $locale, $user_id ) {
       // Perform custom logic or tasks here based on the locale and user ID
       
       // Example: Update user meta with the new locale
       update_user_meta( $user_id, 'locale', $locale );
       
       // Example: Display a success message
       echo 'Locale switched to: ' . $locale;
   }
   
   // Hook the callback function to the switch_locale action
   add_action( 'switch_locale', 'wpdocs_switch_locale_callback', 10, 2 );
