I have an idea for an alexa skill, that requires the corresponding webservice to "think" for more than 8 seconds.
Think of it as of a chess game against a CPU player. The player itself has no limit to answer, because he can invoke the intent whenever he wants on his behalf, but when the player has spoken, the cpu player has to calculate his next move and get back to the player whenever he is ready. This "action" can easily take more than 8 seconds in most cases.
Is there something like a callback directive or some similar notification system, which can help me? Or any better idea, how to implement this idea?
