When US President Biden visited Kiev, it is thought that Russia was made aware of the visit ahead of time for purposes of deconfliction - for example to avoid a Russian attack on Kiev while unaware that they were putting a head of state at risk.
This is supported by CNN's Biden makes surprise visit to Ukraine
And it's interesting because, you know, the expectation had been that with the president here, it might be a quiet day. The Russians almost certainly already knew he was here. They'd be unlikely to do something like, you know, extraordinary, like launching a missile attack on this city while the president was here. But when we heard those air raid sirens, the first thing you want to find out is what type of threat has been reported. In this case, it was MiG activity over Belarus. That, again, is something that we have on an almost daily basis but it does take on pretty loaded significance when you have the president of the United States in a church in the center of town still, Miles, away from the next border, the next border being Poland...
And Wikipedia's 2023 visit by Joe Biden to Ukraine:
The White House stated the visit to an active warzone was unprecedented as the U.S. does not have a military presence in Ukraine, nor a significant diplomatic footprint in Kyiv.19 The visit was the first in modern history that a US leader has traveled into a war zone not under control of the US military.

The CBS News article quotes US national security adviser Jake Sullivan:
"We did notify the Russians that President Biden would be traveling to Kyiv," Sullivan told CBS News chief White House correspondent Nancy Cordes. "We did so some hours before his departure for deconfliction purposes. And because of the sensitive nature of those communications, I won't get into how they responded or what the precise nature of our message was, but I can confirm that we provided that notification."
Now, CNN's Putin makes surprise visit to key city in Ukraine devastated by Russia shows footage of Putin driving a simple passenger automobile, said to be in Mariupol.
The image is notable because this automobile seems to offer virtually zero protection from anything from small arms to an RPG to a large kinetic weapon of the types being used routinely by both sides. Compare to "the beast".
Question: Did Russia communicate President Vladimir Putin's planned Mariupol visit to Ukraine for deconfliction purposes?
Image supporting the question's premise that Putin has been reported to be driving in Mariupol in an ordinary passenger automobile in a war zone, making him particularly vulnerable:
