Control Somfy My Position with Alexa voice control

Hello everyone,

I have linked my Somfy roller blind and raffstore motors with Alexa voice control, which is relatively easy to do by adding the Amazon Alexa Metadata. I can now move my blinds up, down or by percentage using voice control, and the slats can also be adjusted by voice command.

Unfortunately, I can’t manage to move the saved MY position via voice command. I have tried to add the command via actionMappings in the Alexa Metadata:

value: Blind.PositionState
config:
  name: Jalousie Arbeitszimmer
  actionMappings:
    - Close=DOWN
    - Open=UP
    - Lower=DOWN
    - Raise=UP
    - Stop=STOP
    - My=MOVE

The send command ‘MOVE’ is used to successfully move to the saved MY position of the devices, e.g. via rules or scripts:

items.getItem('Jalousie_Arbeitszimmer__Control').sendCommand('MOVE');

It may not work with the added actionMapping via voice command. Does anyone have a hint as to what might be missing or has this already been successfully implemented?
