migration of eSIM from one device to another

How can GP have no online service for migrating an eSIM from one device to another? It is absolutely ridiculous to store a piece of paper with just a QR code for a long period of time without any reason. Since I have purchased the eSIM, I should be able to access it within the app. This is the global standard. Charging 300 taka just to provide a piece of paper is nothing but daylight robbery.
