Set MotionSource value programmatically in C++

Hi!

I’m developing a VR game with Unreal Engine 5.3.2 and C++.

MotionControllerLeftAim = CreateDefaultSubobject<UMotionControllerComponent>(TEXT("Motion Controller Left Aim"));
MotionControllerLeftAim->MotionSource =

Which value can I use here? And how?

In blueprint there are a lot of values, and it could be an enumerate with all of these values?

Thanks!
