3D axis issues from Painter to AE

Hi,

I'm exporting a simple glb ring straight from Painter to AE.

In AE, I've got that 3D circle.

I'd like to have both my ring and circle showed on the same point of view (see screenshot). 

In a front view, my AE 3D circle is well on a front view but my ring is on a side view.

I want to superimpose them as I'll be able to animate both of them.

Actually I'd like to rotate my ring and have a null objet to circle around, which be easy if I could superimpose them .

Thanks for your help. Best regards.
