The Russians didn't even send any high-level representatives.
They sent low-level representatives who can only push demands and not change them. They can't "directly negotiate" (as the Russian government claims they could).
The whole thing is a sham designed so that Putin can claim Zelensky is the one being obstinate, even though he was the one who went to the "direct negotiations" and represents the highest level of the Ukrainian state!
This is so absurd.
