MetaHuman in FPS games

I haven’t found a suitable solution for using MetaHuman in FPS games. I want to separate the models and animations for first-person and third-person perspectives. For first-person mode, MetaHuman doesn’t provide a separate arm model and arm skeleton; its bone hierarchy is roughly like in Call of Duty: the camera skeleton and arm skeleton are at the same level under the root. Is there a reasonable solution for first-person? I think MetaHuman is probably designed more for third-person. Is there any possibility of adapting it for first-person in the future, such as exporting the first-person arm and skeleton when assembling MetaHuman?
