Forms - "Open-access" approval option?


I've created a form that we are using for eTimecards. (Working with a pilot group now)

Currently have the person entering the form also entering their approver's email (approval flow routes to this person as an update to add additional details and approve/deny triggering the next flow)

My initial thought was that it cold route to anybody since they don't need access to the sheet, just the approval/update email.

Is this an option and I am missing a step or do I need to share the workspace with ALL potential approvers?

*note I am working to narrow the approver list down, but would like to have this option if it exsists
