Alembic in Unreal doesn't keep armature animations

Ive created a dress that is rigged to move along a runway. I cant export it to Unreal as an FBX because there is cloth and smooth modifiers that dont transfer. But when I export the alembic it doesn’t keep the armature animation, just the cloth cache

How do I export the alembic with the armature data?

Thanks in advance, Luke!
