Hi Experts,

I am trying to figure out what's the difference and usages of the 2 options for "Request More Information" during approval process:

As the online document says:
Quote:

• Return Options: Select one of these values to indicate the recipient of the information:
  • Back to me: To send the information to the approver
  • Follow approval flow: To send the information to the next person in the approval chain

End quote.

However, I cannot tell the difference from the result.
Can anyone advise please?
