Configure Form Submit Button to Redirect the User to Sales Page

When I offer a form, like an email sign up for lead generation, I use it on a landing page in a very particular way: there is no header, there is no footer, there are no other options for the user than to see what I am offering and provide their email and name to get it.

Current state: user clicks submit and they just see thank you.

Ideal state: user clicks submit and they go to a page that I set in the form settings.

If I had the ability to send them to another page, I could sell them, upsell them, engage them in video content, etc.

Opportunity to maximize having a warm lead on my website. Increased revenue. Better tracking on conversion.

As I prepare to launch more ads that are aimed to simply generate leads, I would like to immediate sell those individuals on time sensitive workshops and retreats.
