Sign a doc with a visible signature

Hello,

How do I sign a document in Adobe Acrobat Reader DC with a visible signature?

When I sign, the document becomes protected but the signature block is blank. I open the signature panel where it shows the document is signed, and valid, but with an invisible signature. I need the signature to be visible. How do I do this? I don't have the option to draw a signature box either.

Thank you!
