If Russia wanted him dead, he would be dead. Russia knows he's a public figurehead. Zelensky is a puppet to his radical nationalist/neo-nazis and now, NATO and the USA.
But since he's the public figurehead, if/when a peace deal is signed, it will be useful to have this puppet publicly sign it.
“If Russia wanted him dead, he would be dead.”
Oh bull, they tried to bump him off and couldn’t. Those Ukrainians are smart and crafty. They have outfoxed Putin and his military time and again.
