Is Russia notified before prominent visits to Kyiv?

There has been several prominent visits to Kyiv since the war started, including U.S. Secretary of State Antony Blinken, US Defense Secretary Lloyd Austin, UK prime minister Boris Johnson, and United Nations Secretary-General Antonio Guterres. Is Russia notified before these visits so they can avoid accidentally triggering a "Pearl Harbor moment", or is it kept a secret? What is regarded as safest, to tell them or not to tell them?
