How to Hide 'Add' Button from specific Goal Plans

Summary:

Hello Community, I want to hide the add button under me>goals and performance> goals from one goal plan but keep it in the other and I have tried these two Expressions in 'visible' field in page composer

#{pageFlowScope.params['pSelectedGoalPlanId'] !='300000144161722')}

and

#{pageFlowScope.pParamsMap['pEvalSectionName'] !='Goals Section A'?true:false }

However, both these expressions made the 'Add' Button hidden from both plans, has anyone tried this and worked ?

Also, is it possible to hide the add button from goals' section in the Performance Document without affecting it in the Goals area?
