What is the function set_offsets for?

I am trying out the function olympe.messages.gimbal.set_offsets() but I don’t see anything happen with the gimbal. I send for example set_offsets(0, 0, 10, 0) and was expecting the gimbal to move upwards 10 degrees but nothing happened.
Can you explain this function further? In your documentation it just sais “Set gimbal offsets”.
I was using Anafi in Sphinx while testing.
