How to install Twitch nodes

Hi,

I’ve installed Lumberyard version 1.12.0.0 with the default install. I’m trying to follow the twitchplay tutorial which can be found here:

My problem is that when I’m looking for the twitch nodes in order to add them to the flowgraph, they do not seem to exist in my installation.

How can I install the twitch Nodes? Couldn’t find any documentation on that.

Thanks
