Using iText7 (C#), is there a way to modify the value in a field to include an href (Link to a website)?

Question

I am working on a prototype using iText7 for C#. The PDF I am using is an XFAForm PDF and was created in Adobe Live Cycle Designer. From my research, XFAForms do not support annotations. I was going to add an annotation to the field with a link.

I want to be able to edit the value in a field to include a URL. For example,

Name : Marc should be:
Name : Marc https://www.google.com

I am able to modify the value in this field, but no luck adding a URL that is clickable. I have tried the following:

1. element.Add(new XAttribute("href", injectedURL)); element is an XElement
2. Injecting HTML as the new value with a link

I was thinking about reading the XML, parsing it and injecting the URL in the XML and then writing it back to the PDF, but I do not feel that is a good solution.

Has anyone been able to do this?
