Source, please. Multiple sources better, please.
Newsweek says "leaked." "Leaked" cannot be verified. Besides, Newsweek states clearly "Strana, a Ukrainian outlet, published details of the purported plan...." And it says, "alleged 100-day plan."
A "purported plan" is not an official plan.
Besides, Newsweek wrote "Zelensky Spurns Donald Trump's Alleged 'Peace Plan," 8 November of last year. So this peace plan cannot be that peace plan. Maybe it's another? Maybe there isn't one finalized as yet? Maybe you have a citation for the "details" by which you commented? Source, please.
Zelensky has agreed to the Trump peace plan. He had no choice.
