Add Filter in mahage roles

hi, 

I'm new (:  I would appreciate your help

How can I ask such a question in mahage roles :

case when (userprincipalname() = '[email protected]' then [KEY] = 81 || [KEY] =82 || [KEY] = 86)

        when (userprincipalname() = '[email protected]' then [KEY] = 87 || [KEY] =88 || [KEY] = 89)

end

thanks (:
