Pre-order from Media Market?

If I pre-order something from Mediamarkt but pick it up like e.g. The ps5 in the near future how does it work then do I get a code that I show an employee or how does it work?

You will probably receive a QR code by email. But I do not know.

You will then have an order by a certain name, you will tell the nice employee that you have pre-ordered the PS5 and they may then ask for the name and order number.

You will receive a pick-up slip by email. You print it out optimally and show it to you in the media store from the warehouse and he will then give you your PS5.
