To hide "Add" button on family and emergency contact

Content

Hello,

I have a requirement to hide the “add” button on family and emergency contact screen for specific roles. 

However, when I try to hide the “add” button via page composer, the settings icon for the commandToolbarButton:”Add” is greyed out.

Steps to get on family and emergency contacts screens: 

• My Client Groups
• Show More
• Employment -> Family and Emergency Contacts
• Search for a person
• Family and Emergency Contacts screen is displayed

Does someone can advise how can I add this button for specific role? I have the EL: 

#{!securityContext.userInRole['DSC_HRBPO_READ_ONLY_DATA,DSC_HR_BUSINESS_PARTNER_DATA,DSC_HR_BUSINESS_PARTNER_APPROVER_DATA']}
