I use a lot the Office UI Fabric, and also the PnP Partner Pack site. One of our customers loved that navigation bar on our custom apps, however we would like to add the App Launcher to our custom apps as well.
This API is not documented,
So I suppose its private and not for public use, if its private, where can I add a feature request to make it available for developers?
If its public, then I am missing something on my implementation (not a JS guy) and would need some help.
