The "hand_l" and "hand_r" control rigs of CR_Mannequin_Body in Unreal Engine are not bound like "foot_l" and "foot_r"

The “hand_l” and “hand_r” control rigs of CR_Mannequin_Body in Unreal Engine are not bound like “foot_l” and “foot_r”. I’m not familiar with control rigging, is there a quick fix for this issue?
