my exact scenario is i have task in scene which will take around 20 seconds. i am giving activation started response to the scene controller request so alexa saying ok to the user. later i have to say to customer like "your <scene> executed successfully" or "unable to execute scene at this time" or "scene executed partially". i want this asynchronous response to be completely customized.
if i keep some text in asynchronous response alexa should speak it. please let me know how can i acheive this.
