Can you use your xbox game pass ultimate for the xbox 360?

Theoretically: if I finally manage to connect my microsoft account from my xbox one to my xbox 360, can I play all the games (that could be played on the 360) from game pass on this console without having to buy them again?

From the Xbox Gamepass Ultimate subscription, only the Xbox Live Gold included in the Ultimate subscription will work on an Xbox 360 console. Although the Gamepass and EA Play also have Xbox, and Xbox 360 games, they do not work through the Pass on the Xbox 360. The Gamepass and EA Play only work on the Xbox One, Xbox Series X | S (if Ultimate or GP for Console selected) and on PC (if Ultimate or GP for PC is selected)
