U.S. final offer with concessions of Ukraine. What's Kiev gonna do?

Today another summit will be held in London with representatives of Ukraine, large Britain, France and the United States. According to the portal Axios, the White home will anticipate Kiev's final reaction to proposals leading to a ceasefire or the end of the war today. However, from the leaks that appear in the media space, it appears that this offer is in many respects unfavourable from the Ukrainian perspective.
