How to add "First Name", "Last Name" text fields after ORKWebView with signature?

Apple's "Research" app "Apple Hearing Study" presents a "California Law" form that requires a signature. The signature field is followed by what appears to be several "body items": a horizontal rule, a "form item", another rule, another "form item", another rule, then some additional text. I have attached a screen shot taken of this display.

Neither the WWDC20 "What's New In ResearchKit", where the ORKWebViewStep with signature was first presented, nor this year's "Build a research and care app, part 1" showed the two form elements following the signature view.

How can text fields be added after the signature view? Can this be done with out-of-the-boxResearchKit or is some Objective-C sub-classing required?

Thank You!
