Getting the error "a3f is not defined"

[akella64]

** I get an error when executing the code from the documentation.**

I get an error when executing the code in this section of your site "https://use-gesture.netlify.app/docs/options/#transform ". I need to understand where to import "a3f" from, to a3f.mesh?

Information:

• Use Gesture version: [e.g. v10.3.0]
• Browser [e.g. google chrome]
