Cannot use v2 functions (i.e. Transparent Background)

[nertilzhuri]

Greentings,

I am trying to render a globe on my page with the demo data, and trying to set the background to transparent and auto rotation to true.
None of the functions described in v2 are working.

Uncaught TypeError: globe_container.setTransparentBackground is not a function
    at (index):86:21

I am using Gio v2.2.1:

<script src="https://cdn.jsdelivr.net/npm/giojs@2.2.1/build/gio.min.js"></script>

What am I doing wrong?
