Exported HTML code - Not showing 'Success' message after form submission

Is there a way to make the Webflow forms show the ‘success’ message in the exported HTML websites’ forms rather than having to redirect to another page?

Here is my site Read-Only: LINK

Webflow Forms will be removed due to GDPR compliance. So you need to stick with something like https://stacket.app which gives you the ability to do so.

I think that is why the redirect, since the action URL was removed or the entire form.
