First step, i install this alpha version of the hunter douglass/powerview app, along with the three different device handlers (room, shade & scene):
Once all set up and i have it connected to the powerview hub, I add the blinds and the scenes that are stored on the hub, in the picture below it has added “kitchen Blinds” for the room kitchen, when in this device it has two options open and close (see second picture)

It has also added three more devices/buttons - these are “kitchen open”, “Kitchen closed” and “Kitchen halfway” - these are scenes stored on the powerview hub - these devices on smartthings are momentary buttons, when pressed they invoke the scene stored on the powerview hub (blinds open, closed, halfway)
Its at this stage that I cannot control these devices via alexa. The alexa app will only discover the buttons for the scenes, not the one for kitchen blinds (just like it natively ignores many other devices like doors or locks). Whilst I can add the kitchen blinds device to askalexa, it still wont let me invoke an open or closed state.
I of course give the askalexa app permission to control all of these devices/buttons, and ensure they are listed in the device list on AWS.
The position Im trying to get to is being able to say “alexa, ask smartthings to open the kitchen blinds”, or “alexa ask smartthings to open the kitchen blinds halfway” - and the corresponding action occur.
