How to get mentions timeline rest api


Hello, I have this code working, but I need to use mentions_timeline, what should I change to get it? in addition to changing the route by … statuses / mentions_timeline.json.
Ive been trying for days but I still can not get results back, I hope someone can guide me.

interface GetUsersShowAPICustomService {
    Call<User> show(@Query("user_id") long userId);
