Is there a coach service from Gongbei to Macau International Airport?

You can take the local public bus AP1 to reach its terminal at Border and then you can pass the border to reach Gongbei on your own.

I am looking for bus service from Gongbei to Macao International Airport. Not the opposite route.

I guest I must go through custom at the border and then take the terminal bus to the airport.
I have been through this custom border gate many times, just trying to find an easier route.

But as I know, it is most convenient to pass the border and transfer to a bus to the airport. So it is still suggested to pass the border first.
