[MCU Infinity War/Endgame] How much does society actually know about the events of Infinity War and Endgame? Cap mentions Thanos in his support group but what about the infinity stones? Does everyone know exactly how Stark and Romanoff died?

It seems like people pretty much know everything. Thanos being responsible for the snap appears to be common knowledge in Endgame and Spider-Man: Far From Home reveals that the actual appearance of the Infinity Gauntlet is known. FFH also shows that people know the nature of Tony Stark’s death, 
they know he sacrificed himself to save the world. 

They know the list of Avengers who died, the only thing they seem to be inaccurate about is that they think Cap died. So it seems like the Avengers were very transparent about the events of Infinity War - and at least about parts of Endgame.
