hide the "Evaluate" button only for the employee based on the section name

Summary:

Hello,

On performance document, we need to remove the "Evaluate" button on "Key Performance Areas" section only for the employee. Requirement is
a. Hide Evaluate Button from the Employee.

b. Allow Manager to view Evaluate button.

c. Allow Employee to view View button once performance document is complete.

We have tried using different expressions below but it either Hides or enable evaluate button for both Outputs and Key Performance Areas.

#{pageFlowScope.pTaskCode eq 'WSEVAL' ? false : (ratingSection and item.Name != 'Key Performance Areas'? true : false) and (pageFlowScope.pDocumentInfoMap['pPerformanceRoleCode'] == 'MANAGER')}

#{bindings.SectionTypeCode.attributeValue == 'REG' and pageFlowScope.pRoleTypeCode == 'WORKER' ? false : true}
