Here's an inteview with one of them from 2019 [1], which would be pretty hard if he immediately died. I have never found any piece of evidence that they immediately died; most sources that say this seem to draw it from the HBO series as if it were a documentary.

That would be strange, because the series didn't show them die. And one of the epilogue screens said: "It has been widely reported that the three divers who drained the bubbler tanks died as a result of their heroic actions. In fact, all three survived after hospitalization. Two are still alive today."
I’ve seen a number of different ends (continuations?) posited for these 3 guys. I tried to research and found about as much evidence that they lived happily ever after as they died immediately (i.e it’s a black hole of conjecture based on the particular writer’s feelings towards the Soviet Union).
Can you point me towards evidence?
