How do you animate 3D - Models in Power Point?

I have a subscription for Microsoft Office 365 products and presently I have the Version 1806 (Build 10228.20134 Click-to-run).

With this launched, I can see under the Insert | Illustrations group 3D Models. After you insert the model you can highlight it and click the Animations Menu item which brings up the  3-D animation related  'ribbon' displaying the various effects possible.

You can create your own 3D-Model using the Paint 3D program on most Windows 10 computers; or use models created by others in the Gallery which is accessible from Paint 3D.

You can then animate the models and even add regular animation as well.

Here is an example of 3D animations on Your tube:
