How to adjust the configuration of when employees can view their evaluations ?

Currently, during the four-step performance evaluation process—

1. Manager Evaluation of Worker
2. First Approval
3. Confirm Review Meeting Held
4. Review and Provide Final Feedback—

Employees are able to navigate to and view their evaluations once the First Approval step is completed. We need to change when this is viewable to after the manager has clicked “Schedule” during the Confirm Review Meeting Held step
