Unknown spherical objects hovering above New York

On March 27, 2022 a citizen from New York captured a series of unknown spherical objects flying through the sky over New York. 


The witness states: I recorded this from my window something drops something that looks like balloons but I'm not sure.

If you look closely you see when the video starts at the top right it crosses something that looks like a flying saucer but I only realized after watching the video.
