My understanding is that there isn’t really any evidence supporting the official story of Hitlers death, his supposed corpse has been proven not to be him (and in fact female) and everyone from the Stalin to declassified FBI files indicate it’s extremely plausible he escaped.
We also know there was large Nazi communities in Argentina following WW1 and it’s possible many WW2 Nazis could have escaped to rural Argentina as a safe haven.
How do historians view the official version of events, that Hitler died in Berlin by suicide?

You may be interested in the FAQ section "Did Hitler survive the war?". In the app, the # URL anchor doesn't work, so you'd look for the section near the bottom of the page. The two users mentioned there are /u/Bernardito and /u/EtherealEther.
