Edit three js animation

I'm looking to get quotes for adding some animation/features to an existing three.js animation you can see here: https://www.aca-3d.com/clientarea/328/DA/, there needs to be some interactive buttons to allow a pop-up to appear showing more features of the plane - 7 in total, you can see the static version of this on this website: https://www.deutscheaircraft.com/products, and a copy of this brief can be found here:
