Modular characters

Hi guys , im a starter with UE5 .
I got a question . I got some modular characters with rigs but i would like to cut them for more parts , for example i would like to separate the arm mesh into 3 pieces .
I tried to export the rigged character from UE5 to Blender , but when i cut it , and export it back to UE5 the animation on at the cut part looks distorted and weird .
What is the proper workflow of creating modular characters with rigs ?
I cant find any good videos on youtube . Could you pls help with any advice ?
Thank you .
