How is FXS inherited?

Could you elaborate on the process of how FXS is inherited? Specifically, I'm interested in understanding the technical and legal aspects surrounding this process. Does it involve any specific requirements or procedures? Are there any restrictions or considerations to be made for those inheriting FXS? Furthermore, how is the inheritance handled in terms of security and access to the relevant wallets or accounts? I would appreciate a clear and concise explanation of the steps involved in inheriting FXS, as well as any potential challenges or implications that may arise during this process.
