uml - Use case diagram: of several actors of a use case, only some have access to an extending use case -

how can represent diagram in several actors have access same function, or "use case" of them have additional functions or "extends" (if im right) within it, if extend on main "use case" mean accessible right?

when utilize case extends main utilize case, extension points @ main utilize case, can have conditions. status specify specific actor.

if actors can generalized, have seen solution too. prefer first 1 because not sure if technically right (as noted, extend utilize case default accessible everyone).

hope helps.
