Hey @mvandrei, first let me thank you for answering!
I’m using the Copilot free plugin, but it’s like all the other OneSignal plugins I guess? (I mean they are all working with Player ID in order to send notifications through the API)

According to Nativator support :

Getting the player id is done from you end or on your One signal account.

And they definitely won’t help for this, and I thought they would when buying
