Adobe sensei - Autotrace

[Ciellchan]

Hello! I've seen the Illustrator for iPad has a feature of autotrace sketches and adjusting them to the grid, the thing is I can't find it. (I'm attaching a gif of someone using it)

I tried taking a photo and importing a sketch and the portraited feature does not appear on my options.
How can I activate/use it? 

Thank you very much in advance!

This might be a prototype sample of something being worked on.

It is not available in Illustrator on the iPad at this stage though.

Thank you! I thought it could be the case but I was unsure, I saw it on an article at "The verge" and thought it was already available. I hope they add the Sensei soon!! 
Thank you very much for your answer!
