Adding 3D CAD to a custom 3D scene as background

Hey community

I am currently designing mockups of some energy gen equipment to be placed at a site (facility). How can I add the facility's 3D image as my own custom background, like the “Ambience” mode in CATIA 3DExperience?

 

For example, how this video has the model of the plane with the hangar in the background that has a 360 view- https://www.youtube.com/watch?v=d_otm4-ovZs 

My end goal is to be able to show the clients how I am proposing the placement of the equipment to be at their facility, rotate the scene with the added equipment in CATIA to give a 360 view and a rough spatial idea.

Thanks
