Hide Check In region from Worker based on Review Period or Template EL Expression

Summary:

We have an existing EL expression on the Check In region to hide the Check In region from the employee:
#{pageFlowScope.pLoggedInRole ne 'WORKER'}

This expression works just fine. We need to add a review period OR template name/ID parameter to this EL expression. To hide the Check In region only from employees only for a certain review period OR certain templates.

We see these parameters are available in page composer for this region:
#{pageFlowScope.pLoggedInRole}
#{pageFlowScope.pMatrixManagerLogIn}
#{pageFlowScope.pReviewPeriodId}
#{pageFlowScope.pAssignmentId}
#{pageFlowScope.pPersonId}

Please advise, we have tried to add #{pageFlowScope.pReviewPeriodId='300000012470767'} and #{pageFlowScope.pReviewPeriodId ne '300000012470767'} these are not working at all.
