Not being able to log Standard Events

[hhanckes]

I am not being able to log a Standard Event in Facebook like Add To Cart or Purchase (https://developers.facebook.com/docs/app-events/getting-started-app-events-ios), how can I do it? Can you share an example?

I am currently doing

const facebook = require("nativescript-facebook")
facebook.logEvent("Purchase");

But it generates a Custom Event named Purchase not an Standard Event that's recognized by Facebook.

It occurs in all platforms and versions.

Thanks!
