Combine EL expression

Summary:

Content (required):

I am trying to combine two EL expressions so that an icon on the navigator is only visible to certain users in a role but also excludes users in another role. The two expressions I am trying to combine are:

#{securityContext.userInRole['EBK_ORA_PER_HUMAN_RESOURCE_SPECIALIST_JOB,EB_HIRING_MANAGER_ABSTRACT_CUSTOM,EB_RECRUITER_VIEW_ALL_DATA']}

AND

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