Export only camera to Alembic file?

I am trying to export just the camera to an alembic file but somehow, I get the mesh in the scene too.

https://docs.blender.org/api/current/bpy.ops.wm.html

I have tried selected the camera and exported selected=True but that still pull in the mesh.

Any idea ? I am using Blender 2.82

Cheers

Select the Camera. When exporting check Selected Objects.
