Assign values to hidden fields in native forms

Assign values to hidden fields in native forms

It would be great to be able to assign values ​​(static or dynamic) to hidden fields in a form. Currently, I can only assign a value via the URL.

I currently have a form integrated with a webhook, but I don't have a way to send useful form data as parameters, such as the form name or the source URL.

Another option I can think of is to be able to hide text fields in the form, similar to how Zoho Forms works.
