Hello Alex, thanks again for your response. I am using the SDK in my Android Kotlin app, so I am not sending notifications through the endpoint, but directly from the callUser function.           fun callUser(user_id: String): Call? {
      val sinchClient = sinchClient ?: throw RuntimeException("Sinch Client is not created")
      return sinchClient.callController.callUser(user_id, MediaConstraints(true))
    }           I have implemented everything from the push examples and the documentation, but I’m not sure if I’m missing something since I haven’t been able to receive calls.
