Xbox - Multiplayer - Game Pass

At the moment I have Xbox Game Pass Ultimate, but am wondering what is the minimum Game Pass required to still be able to play multiplayer in MSFS? I can recall reading that mid to late last year that Microsoft changed the multiplayer requirements and that Game Pass is no longer required can anyone in the know please clarify?

If you own the game then I’m pretty certain you can get away with just having Xbox Live.
