OneDrive request for keychain access

Today, when I turned my iMac on, a pop-up request from OneDrive appeared. It reads, OneDrive wants to use your confidential information stored in “Microsoft identity AC57033A-AC9F-A13E-F6B34BC8E09D” in your keychain.

I don’t know what this is and . . . when I search for this in keychain nothing is found.

Has anyone had this happen? It’s irritating as it keeps popping up even after I repeated click, Deny.

Thanks,

Dave
