The Stemme S12-G constantly banks right

I purchased the S12-G from the MSFS2020 store.
As shown in this video, the S12-G constantly banks right and cannot fly straight.
This phenomenon persists even when the engines are shut off and it’s gliding.

If you look at the Input Viewer, you can see it banking right even though the ailerons and rudder are in neutral.
Of course, the engine is off.

Is there an aileron trim somewhere?
