How to define First Responder Wins Work For Two Approver Groups in Purchase Requisition

Summary: Currently, Capital Requisitions are approved by approval group - Eg. SCM Req Approval - as first responder wins.  that means Approval Group consists of 4 people whoever approves it, it will get approved (First Responder Wins)

We would like to insert a new approval group - eg. FIN Capital Approval - also as first responder wins, before the SCM approval group.

Basically, we want the FIN group to have the first opportunity to approve/reject the req, then we want the approval to move to the SCM approval group for approval/rejection.  Created this scenario in TEST (see attached), but all members of both groups - FIN and SCM - received the approval notification at once. How do I set up the rule to produce intended results?
