You mentioned "adding value" a few times, but if you are truly job shadowing then that should not be a goal of yours. Job shadowing is about observing and learning. Just watch and listen, and do your best to humbly stay out of the way.

Thank you. This gives me clarity. My need to contribute was my way of showing him how grateful I am, but that can come at a later time.

Totally understandable. Later seems appropriate, and your feedback after completing this process will probably be pretty valuable to your friend.
