What if I inherit bitcoin from a deceased person's Coinbase account?

I'm curious about the process of inheriting Bitcoin from a deceased person's Coinbase account. Could you explain the steps I should take to ensure a smooth transition? Firstly, how do I gain access to the account? Do I need to provide any legal documentation? Secondly, how is the value of the bitcoin determined at the time of inheritance? Are there any taxes or fees associated with this process? Additionally, is there a way to transfer the bitcoin to a personal wallet for safekeeping? Lastly, what should I be aware of regarding the security and privacy of the inherited bitcoin? Any advice you could provide would be greatly appreciated.
