Teach Spouse About Seeds And Retrieving Our BTC Should I Unexpectedly Die

Has anyone done this?

Were there any helpful resources that made the process clearer and give the needed knowledge to take control of the family stash?

I don't want my spouse to have to spend the time I've spent to understand Bitcoin. I simply want them to be able to manage the coins should I not be able to do so. The coins are currently in cold storage on a hardware wallet. Seed is stored on steel. Passphrase has been added.

Thanks!
