I have a JSObject that runs on page load and displays a success message. However, I want to suppress this message or use my own message. I realized that this issue has been recently fixed in the deployed app.
The solution was to not worry about the success message on page load for a JSObject, as it was recently fixed in the deployed app and no longer shows. This was confirmed by testing in the deployed app and checking a closed issue on GitHub. Therefore, no code examples or changes were necessary.
