Alexa "Echo Speaks" Functionality

I’ve seen a few videos lately on smart home things that utilise a SmartThings skill called Echo Speaks to pass actions to Echo devices via a routine based on virtual device statuses

I know we can do Virtual Devices with Homey but the piece we’re missing to my knowledge is passing things to Alexa routines

I’d love to be able to do this (I can push FROM Alexa but so far no way to push TO Alexa) as Alexa is the heart of my smart home

Any way to get this working?

Is how you push TO alexa.
