alexa configuration

Hello,

I have question about the configuration of Alexa in french .

I managed to control a light knx (on / off, variation) but for the doors or roller shutter, I can't get the controls are always "on" and "off" and not "open" or "close".
however, I put in "Alexa Display category" the value "DOOR" instead of "LIGHT". The link knx is made on the property "Power Reference" is this correct?
Do you have documentation on the configuration and associated commands?

Best regard
