How to create new users in OneSignal?

[wxmerkt]

If a new user installs the app on a new device after the initial data import, how can a new user be created in OneSignal? Will the push adapter take care of this automatically? If not, what steps need to be taken for a new user to correctly work with OneSignal

Thanks,
Wolfgang

I can see that if you connect it just on server side (parse-server), users are adding up to OneSignal users list (no OneSignal SDK installed on the app).
Yet, The push doesn't work. Not from cloud-code and not from OneSignal dashboard which probably means something with the adapter isn't right (install base parameters isn't correct).

I wonder if using the SDK inside the app would resolve this or just make it work sometimes...
