We are currently integrating the OneSignal Plugin in our ODC environment.

1. Registration Issue:
   • When using the Register action, the device is successfully added to our OneSignal account.
   • However, the output parameters (PushToken, OneSignalUserId) are returning as empty, even though the registration seems successful on the OneSignal dashboard.
2. PostNotification Error:
   • We are attempting to use the PostNotification action by passing the SubscriptionId of the registered device.
   • However, we receive the following error:
   • Note: There is no input parameter to pass the API key in the PostNotification action

Please assist in resolving:

• Why the Register action is not returning output parameters.
• Why the PostNotification action is failing even without having input api key and getting below error
  
  Error: Access denied. Please include an 'Authorization: ...' header with a valid API key (https://documentation.onesignal.com/docs/accounts-and-keys).
