Thrustmaster Airbus set and B737 speed brake (spoilers) settings

[Soky]

Hi.
Does anyone know how to set up speed brake (spoilers) for Thrustmaster Airbus captain set?
In MSFS 2020 works spoilers lever fine for Airbuses, I didnt try Boeings there.
But in MSFS 2024 I cannot set it for B737 (Airbuses are completely unplayable).
And I cant set the speed brake even for keyboard buttons. What the ♥♥♥♥ Im doing wrong?

So, if anyone knows, I will be glad for help.

Thanks.
