Polling, the ugly way, but the compiler tells me c will always be null:

cardScope.launch { 
                            var contact: WhatsAppVideo? = null
                            while (contact == null) {
                                delay(500)
                                contact = getContact()
                            }
                            callContact(c!!)
                        }
