Question about DJI Care Refresh

Hoi zäma. Can anyone tell me how this Care Refresh should work? Will I receive a letter in the post from this external provider, Modellsport Schweighofer, with an activation code? I received the drone today. According to the order summary, the Care Refresh is "ready for shipment from external warehouse". I am now activating my drone and should order or activate this Care Refresh within 48 hours according to the DJI Fly App. Many thanks for a few tips and greetings
