Passing down Bitcoin after death

I have family that have no idea what bitcoin is and how it works. Truthfully, even if I say them down they would not understand. If I were to die, how could I make sure they get access to my bitcoin?

I feel like they would need to know so much about bitcoin, jargons, scams, seed phrase, wallets, etc.. to even know what this is and how to redeem.

With my 401k I think that would be easy and straight forward they’re able to call and talk to someone about that. But what are we doing about our cryptocurrency?
