Pass external function to a class method

I would like to understand how to pass an external function to a class method. For example say I am trying to call a function 'job' every second.

import schedule
import time

def set_timer_minutes(func):
    schedule.every(1/60).minutes.do(func)

def job():
    print("I'm working...")

set_timer_minutes(job)
while 1:
    schedule.run_pending()
    time.sleep(1)

The above code prints 'I'm working' every second. But if I try to put it in a class

class Scheduler:
    def set_timer_minutes(self,func):
        schedule.every(1/60).minutes.do(func)
        while 1:
            schedule.run_pending()
            time.sleep(1)

def job():
    print("I'm working...")

x= Scheduler
x.set_timer_minutes(job)

I get

TypeError: set_timer_minutes() missing 1 required positional argument: 'func'

You need to create an instance of Scheduler.

x = Scheduler()

instead of 

x = Scheduler
