Hi Sadae_1,
Welcome to the Apple Community.
We are all Apple users, like yourself, in this community so we can not speak for Apple itself.
We'd like to help, however.
Apple's Pick-up info is available on this webpage: (link below)
Shipping & Pickup - Shopping Help - Apple
Eg: Scrolling down to "Apple Pickup"
says
"In some instances, you may also be able to select a window of time to pick up your order at an Apple Store.
This Check-In Window will ensure that your order is available shortly after you arrive.
Just check in with a Specialist when you get to the store.
If you’re unable to come in during this time window, you can pick up your order afterward, but wait times may vary.
You'll receive a notification email when your item is available to pick up.
Please wait for this email before coming to the store."

There's a lot more pick-up info. on the above webpage itself.
______________________________________________
When choosing a product online / placing an order / etc., there is generally the option there to speak with a specialist.
(Sometimes it is as simple as clicking on a small round photo of the specialist.)
A specialist may be able to give more specific info. about your in-store pick-up in the particular country.
There is also shopping help available from this webpage, eg: for finding answers to questions that may arise:
Help - Apple
or
If needed:
Apple phone numbers around the world
Contact Apple for support and service - Apple Support
All the best :-)
