You can add forms to Super, and we recommend using Tally.so to do this. Tally works really well with Notion and also with Super.

Please check out the guide from Tally.so: https://tally.so/help/how-to-add-popup-forms-to-notion

If you run into any difficulties, please be sure to contact Super support in the Intercom chat bubble in the lower right of the browser window.
