EL Expression: Employee should be able to Edit even if they have Manager Role

Summary:

We need to accommodate a requirement in Personal Details > Family and Emergency Contacts Page wherein in ESS, all employees should be able to edit while in MSS - all Managers must have view only access to the page.

Note: HR Should be able to edit as well.

This is a shared component in Page Composer and an EL Expression below is not working if the user has both Employee and Manager role.

#{!securityContext.userInRole['MANAGER_ROLE_CODE']}

Question: Is there an EL Expression code where for MSS or ESS?

For example - if the page is navigated from My Team tab, then read only.
