When the Flow Approval is generated, an automatic email sent to approver contains two variables: Requested for and Created By. Requested for is a person that requires the approval. Created by is a person that designed the flow and this variable should be hidden (not visible to the approver). Is there any possibility to achieve that?
The "Requested for" field in the email is mapped to the "Requestor" field in the Approval action. It can be edited but it cannot be empty.
I cannot find the source for the "Created by" field in the email. Initially I thought it was the owner of the Approval connection, but that is not the case.
I know this is a partial answer, but I thought it might save you some effort.
