In Need of help

Hello,

I am trying to figure out who shared a superbowl sheet with me. It has since been deleted and these numbers were there 

fc09f9a1-00f2-b000-e8d4-ca3f2fb6248c7787c. Is there a way to find out what they are for. Is it from the sender or is it something on my end. Any help would be appreciated.
