How make package for win10 app store

I’m using visual studio 2017 and cocos2d-x v 3.16.
I can compile and test my game by pressing the local windows debugger button.
But I can not understand how to create the package.
In some guides we talk about a Package.appxmanifest file that I can not find among the project files.
Also I should see a store command by right clicking on the project, but not even the shadow of that command.
What am I doing wrong?
Can anyone help me?
Thank you!!!
