How to enable "wix form data" for automation?

I was trying to create a email notification for the custom form via collection I created. However, I didn’t see the “wix form data” option as an option on the automation creation page. Here is the screenshot of what I could see.

Did I miss any other configuration?

Thanks!

It turns out that the site has to be published for the “Wix Data Forms” to show up as an option when creating automation.
Thanks to the Wix support team!
