Regarding Modern warfare 2019 & Modern warfare 2

Hi guys, I would like to ask, regarding these 2 games Modern Warfare 2019 & Modern Warfare 2 (2022). Since I do own a game of Modern Warfare 2019, I like to know if the 2022 version of the Modern Warfare 2 game is linked to our 2019.

Because right now the confusing part was Activision provides this game but so does steam. So is it a separation of games and previously we unlocked the item is not going to be relevant?
