Inserting a digitally signed PDF to an article

I need to add some digitally signed documents (pdf format) to a report I’m writing and, for some reason, when I import the document both the document’s number and digital signature are gone. Documents signed through a web application and are numbered once they receive their final signature.

This is the command I’m using:

includepdf[ pages={1,2},pagecommand={subsection{AGG}}]{AGG.PDF}

This is an image of what the digital signature looks like and what is missing on the final document where this is imported.

Is there a way to have digital signatures show on Latex? I’m using Overleaf if it makes any difference.
