Displaying sharethis widget on thank you page

I am trying to display a social media sharethis widget on the thank you page. However, its not working. Is the thankyou page capable of using embeddable code?

We have restrictions, and embedding script code is not possible. What you can do is to create your own Thank You Page where you can embed the code, upload it to your server and redirect to that URL: https://www.jotform.com/help/38-Redirecting-Users-to-a-Different-Page
