How do I add a hyperlink into a document sent for signature via Adobe Sign

Please help with this ASAP. I understand this feature used to be available in Enterprise edition.

I have a PDF document. It is a booking form. I have inserted URL links into the PDF taking people to privacy policy and a payment link page. When I upload the document to Adobe Sign and take it through the process to be ready for signature the document looses the clickable link. The text remains but the link itself is no longer recognised and Adobe Sign only directs the user to the signature fields.

How can I solve this issue where I would like the customers to be able to click on a link within the Adobe Sign document before they sign.

Please let me know ASAP and I will be very grateful.

Thank you,

David
