Promisify of Express middleware

How to promisify function what is Express middleware (for example authenticate(arg1, arg2)(req, res, next))?

I tried promisify method from util and also from es6-promisify but none of those work. I am getting error:

TypeError: authenticate(...) is not a function

when I do:

const authenticate = promisify(passport.authenticate);

(passport.authenticate) is the middleware.

My actual problem is: I am using passport-jwt module for passport and I want to reuse passport.authenticate middleware as normal isLoggedIn function. I do not want to make same function to check JWT when there is this function. Also I do not want to promisify this middleware manually because I will be doing it in many places and its code repetition.
