So Boris Johnson didn’t fly to Ukraine to tell Zelensky not too make an agreement but to keep fighting ?

Yes, Johnson did advise Zelensky but there was no agreement at the time. Nor was there any real hope for one. The Russian demands were too great. And what ended the negotiations was not Johnson's visit (negotiations continued after it ) but the revelations of the Bucha massacre. Public opinion in Ukraine turned against negotiations; they were not ended because of instructions by Johnson. Let go of that Russian propaganda.

So you say,
most others don’t.
