That’s something the plugin has to handle, since it’s client-side. Make can’t perform the redirect since the script did not send your user to the Make webhook itself, but only the form data.
Hope this helps! Let me know if there are any further questions or issues.

P.S.: Did you know, the concepts of about 70% of questions asked on this forum are already covered in the Make Academy. Investing some effort into it will save you lots of time and frustration using Make later!
