How to send to new URL after submission?

Hello, I am trying to use the gated content form to send the user to a new URL after successful submission (the use is for gated content webinars – the new URL page has the full video playable).

I tried this: https://imgur.com/Thezr1Z and this: https://imgur.com/9bv1L74 but when the form is submitted it just shows the thank you message (I can’t add HTML URL message there) and not the download box because I can’t “set gated content” with a page URL, it only wants a selected media item.

Please have in mind I have very little coding knowledge so would appreciate a more detailed tutorial how to do it effectively. The best way would be that after successful submission, the user is immediately transferred to the new URL. I only need the redirection to be valid for this specific form, not in general for all.

Thank you for taking the time!
