How do I make the Document Recovery Task Pane visible again?

Help! My "Document Recovery Task Pane" is no longer showing up on the side, does anyone know how to make it reappear? I can't believe I can't find anything online for this?

I have tried all the various ways to manually recover my documents, but none have turned up anything. However, when I attempt to close out of Excel, I am given the prompt asking if I want to remove the files or if I want to view these files later, so I know the files are there.

I am just looking for advice on how to make the pane visible again?
