Any way to stay on WP site after form submit?

I’m using WPMautic to place a simple email sign up form in a post. It triggers an automated email, but in the process, it sends the visitor to the default Mautic confirmation page (or default message page). Even if I set the Mautic form to “Stay at Form”, the embedded form on WP ends on the Mautic URL.

Is there any way to keep the form submission from redirecting to the Mautic installation, and remain on the WP page that the visitor has submitted the form from?
