Hey, I'm having a difficulty in previewing a form from another entity that has one same field with the previous form.
So I'm having a token authentication form here in an entity form from the entity OTP. I'm not showing email field but there is a field called Email which already has data in it.

after submitted, I intend to redirect this page to another page that shows a form in edit with another entity which is Applicant that has the field Email with the same value as the one submitted in token authentication form, however, the form is not showing up

On portal Management I've set the parameters as below, I think it has something to do with Append Attribute Value to Query String - Parameter Name or Logical Name however I have no idea what I should fill there if it is indeed the issue.

I'm also thinking about using flow to show the desired form, however I don't seem to find any way to display form through portals using flow.
I'm really stuck there.
