Capture reason for not signing a document

Hi,

I am working on a SharePoint solution and I am using Power Automate to send documents for signature and then storing the signed doc as a pdf along with the relevant metadata within designated columns in a SharePoint library. The snag I have hit is when signing the document is declined by the signer and they give a reason, I wish to capture that reason and store it in a column in SharePoint.

Is this possible and if so, how???

Appreciate any and all help, thanks!
