How do we set up approval workflows for direct deposit changes?

We want to set up approval workflows for direct deposit changes so we know and can verify it is the employee asking to change their direct deposit. How do we set up this type of workflow?

Right now, we have a system-generated email that goes out to employees when they change their direct deposit to say if this wasn't you contact the HR Office. However, when we run a report as part of the payroll process, it is generating false positives and sends out these emails even when the employee has not changed their direct deposit. It is creating concern and panic among employees and our security team. We think setting up approvals will be a better solution than having a system-generated email.
