Can't see Key Influencer Visualization

Hello everyone!

I am running on this version of PBI desktop, and have been eyeing several threads regarding Key Influencer visuals, but can't seem to find a definite solution.

I read (here: https://community.fabric.microsoft.com/t5/Desktop/Key-Influencer-Visual-not-visible/m-p/672927#M323845) that you either need to have the .net 4.6 version at least, or to go to Preview Features and then enable this visualization. On the first one, I'll get my TI team to install it, but what worries me is that I can't find the "Preview Features" menu on the options menu:

Any idea on how to fix this?
