>> Roles and Events

Good morning,
Happy to discover Events+ these day !
A big question this time :
I create different roles, name here RoleA and RoleB
I use "if menu" plugin to hide link to specific roles
RoleA see page A and RoleB see pageB
Theres 2 events types : EventsA and EventsB
How can I do to have Events only visible for a specific role ?
ex: EventA1 visible only by RoleA

Thank you very much
