How to import FBX camera and use it properly

I'm learning about the new camera on the Mocha Pro. Exporting the camera data in a FBX file is easy, but then importing it into Fusion and aligning it to the image plane seems complicated.

Nothing is too small.

What's the proper workflow for using a camera from an imported FBX file?

I know that Fusion has its own camera tracker, but sometimes tracking is already done in Blender, Mocha, and other applications.
