What if I told you that Elsa actually died in the finale of Frozen Two? In order to learn the truth, Elsa sacrificed herself for the souls by ignoring the warning and going deeper into the cave where the memories of the past were kept. That's why Olaf loses his magic and begins to disappear. Anna even says this. After the dam collapses and the five elements unite in the sky, Elsa's frozen state breaks down, but she fall even deeper and we watch the moment she actually dies. When she met Anna on the shore, she was no longer in human form, but in the form of water and ice memories, that is, she turned into the fifth spirit. Even pay attention here. Here she does not answer yes because she is just a spirit. In the finale, Anna wears the crown because Elsa can't. So why does she send the message to her sister with the wind spirit? Because this is the only way human world and spirit world can communicate.
