Doing a bit more investigation on this, the ‘bot’ integrates in Slack and is basically another Alexa device in your Amazon account. This was written by an individual company, not Amazon, and while they seems legit, they admit the backend database DOES have access to your information (what you have typed, probably login stuff, etc).
Push is something that Amazon doesn’t allow except in very certain aspects…While skills like Ask Alexa work with this bot, at the end of the day this is no different than the simulator available on the Amazon developer site. The CAN push to Sonos speakers (with specialized skills), but you will never be able to have direct output from Alexa until Amazon turns on the push functionality, and then it will require the developers to modify their skills and the best we can expect is a yellow ring to illuminate on your device, and you will still have to speak to it to get the message.
Hope that helps.
