For the animation saved by livelink, how does UE5 export the value of the MorphTarget curve of this animation to an external script file?

In UE5, the character is controlled through livelink and an animation is recorded, and then the animation is saved in the project. In the saved animation, each expression controller (corresponding to the deformation target in UE, MorphTarget in English) corresponds to a curve, and the fluctuation of the curve To reflect the change of the value of each expression controller, how to export the value of the curve as a script file to the outside of the project?
