OP isn’t American. It’s not a universal euphemism.
Even having lived in the US at one point it’s not an automatic connection.
Canadians (at least in my experience) use the expression ‘passed away’ if at all to avoid saying ‘died.’
But also being Canadian, I’ve given my regrets elsewhere on this thread. And I’m sorry for the unintended shock to any and all who don’t share my dialect.
