Meta Quest 2/3 - Naming Convention/Official Terminology

Hello Meta, 

We are looking for documentation that covers the official naming convention/terminology for the Meta Quest 2/3.
These should convey what terms we are allowed to use in our applications when referencing the hardware buttons or software elements.

Is there such documentation, with the official naming in different languages you currently support?

If not, what is the best practice when making text references to the controller/headset buttons, or other software elements.

Thank you in advance,
