Stalin's daughter Svetlana in a new yorker article wrote that she witnessed her father dying, but I have also read that he died alone in his room. Which account is true?

In a New Yorker article Stalin's surviving daughter explains:

"In March, 1953, Stalin had a stroke. Svetlana wrote, “The death agony was horrible. He literally choked to death as we watched. At what seemed the very last moment, he suddenly opened his eyes and cast a glance over everyone in the room. It was a terrible glance, insane or perhaps angry, and full of the fear of death.”

My previous understanding was that Stalin died alone in his bedroom, largely because the people around him were afraid to wake him/enter. Is there an accepted historical account of how he died and who witnessed it?

meh, I feel a little silly now... a quick google search revealed that he did have a stroke alone in his bedroom and was found in a sad state, but that he lingered for a few days before actually dying. Would still be happy to hear anything an expert would have to add.
