Had same problem !
Now using 3.0.9 SDK
and this code for Init and Prompt
internal async void InitializeOneSignal()
{
Debug.Log("Starting One Signal Init !");
OneSignal.Default.Initialize(m_OneSignalAppId);
var result = await OneSignal.Default.PromptForPushNotificationsWithUserResponse();
Debug.Log("Notifications_PermissionChanged - " + result);
}

and its working :) also i am on Unity 2022.3.x if it helps :)
