Where can I read information about the offline operation of yandex mapkit?

Question

Android

Hello!

I can't find any information about how yandex MapKit works offline.
In "Licenses and tariffs" there is an item "Working with the card in offline mode"
The customer wants the card to be able to work offline.
And now I need to know if it is possible to load tiles in advance for the region / city of anything. Whether data storage needs to be managed. What are the restrictions on this. What API.
Or Yandex maps do not know how?

Help me please!
