in my case i need to identify my app's user by their unique device id. i have came across a solution by getting id using SystemIdentification.GetSystemIdForPublisher(). But i also came across a stackoverflow question where the id is getting duplicate across other systems.
https://stackoverflow.com/questions/61352554/getsystemidforpublisher-doesnt-return-unique-id
Kindly help me with the right fuctionality to achieve my case.

Derive from the official document, when the source is Tpm or Uefi, it can make the device id unique. If the source is Registry, it can’t guarantee that the device id is unique.
