Indeed, the plugin loads remotely every time you use the plugin command. If you make changes, you should be able to see those changes in real-time.
Keep in mind that due to the intricacies of how the internet works, including DNS, caching, and update times, the changes may not be 100% instantaneous. However, I can assure you that the plugin dynamically retrieves information.
The plugin also has support for scenarios where the user doesn't have internet access or there's a connection error. In such cases, it prevents the connection and returns an error message like "connection error" for the Open Online Text Window, or you can activate a switch when making a fetch (a request). If there's no connection for any reason, this switch is triggered, and you can then handle conditions as usual in your events. You can find more information about this in the plugin's help section.
Best regards!
